>Revolutionary new cartridge that blows all that old shit out of the water so hard that they had to design a fricking 3lb pistol to be able to contain its power

Someone explain this shit to me.
I can't. They went with a strange bullet size that's just a hair smaller than .308/7.62 as to make using widely available .308/7.62 bullets impossible in the gun. Meaning proprietary ONLY, meaning reloading and cheap(er) ammo is unavailable, you buy their cartridge at a premium only.
The saving grace is the 10mm offering which is one of the most versatile pistol cartridges ever made. Load it down to .40S&W levels, or load it hotter than most commercial .357 magnum.
Just a smaller weaker 9x25
Kinda this, though 7.5 FK does have superior sectional density. Though it may be only marginally better? I'd like to see them tested side by side out of matching barrel lengths in the same mediums and against the same hard targets on the same day to get a really good comparison of their performance.
My back of the envelope math tells me that 7.8FK would penetrate 2.13% more than 100gr 9x25mm.
I'm not certain that 2.13% is gonna matter, because either way it's definitely gonna go through IIA and possibly IIIA.
just adding because I'm not sure other anons know about the glory that is 9x25.
That is pretty sweet.
It's .001" smaller. Close enough to use .308 projectiles
It being .308 isn't the problem, doofus. What do you think you're going to do with a .308 projectile in a handgun cartridge? Nothing would fit in the mag. It NEEDED a .312" bullet diameter so it could use .32 ACP bullets.
On the other hand, you should be able to use 7.62×39mm barrel blanks for a hypothetical 7.5 FK Vityaz, since they're the same diameter and the common rifling twist is pretty close.
You have my attention
They're not at all the same diameter.
7.62x39 is .312", 7.5FK is .308"
While tolerances for bullet and barrel sizes typically allow for 1-2 thou difference, they don't allow for that large of a gap to be crossed.
7.62 Russian and 7.62 NATO are different sizes.
The bullet diameters are within tolerancing for standard manufacture.
Why would anyone want to use .32ACP bullets?
They're all short and fat for their chambering. Exactly what you don't want in a cartridge like 7.5FK.
>Exactly what you don't want in a cartridge like 7.5FK.
Unless you want an 80gr JHP to go 2200 FPS, or even a 60gr JHP at 2450. The main issue I have with 7.5FK is that it uses weird SCHPs that just break off the tip and have wadcutter terminal ballistics. It's great for hunting, but terrible for a defensive handgun when it has the incredible potential to do so when it has the ability to approach 5.56 SBR ballistics.
They have the potential to. See above.
If you wanted that you should go the direction of necking it down further to .22 or .25
You want rifle style longer and thinner bullets to make the most of that velocity. Not fat and stubby pistol bullets that have.
Fricked up that last sentence
>Not fat and stubby bullets that pistols have
LOUDENBOOMER!
Velocity actually seems low, .17 caliber 5000fps rounds are proportionately smaller.
Shit, those 4k numbers are achievable with 22-250
>.17 caliber 5000fps
What? The only 5k fps I've heard of is .224 McDonald. Are you talking about the .17 Incinerator April Fool's joke?
He's probably talking about the .17 Super Eyebunger... seriously, that's what it's called.
You can't just neck down until you get small enough bullets. The further your cartridge is necked down, the more barrel it needs to get its full potential. I bet you would just barely crack 700 ft lbs if you necked it all the way to .22.
Nobody would ever do it. You would need some absurd pressure. Your best bet would be:
>Desert Eagle with beefed up bolt and 10" barrel
>bimetal case .429DE with 60gr .32 bullets in sabots
>pressure cranked to 50K PSI
Quickload claims 3400 FPS with realistic powder charges. That's doing some insane bullshit that pistols really aren't good for, though.
Sure, you can't infinitely neck a cartridge down, but you need to account for bullet design first, and then find your diameter afterwards.
There aren't any good .32ACP bullets for light weight purposes like these. The diameter vs length ratio simply is all wrong for proper high speed ballistics.
If you're aiming for 60-80gr projectiles, either you need to change the construction of extant 7.5FK projectiles internally to achieve that, or you're going to have to neck it down further to maintain proper bullet design. Otherwise its velocity is being substantially wasted on the bullet design.
You keep saying you need long bullets for high velocity, but why? It reduces the range, sure, but what negatives could it have as a defensive handgun round?
Range, sure.
But also long and relatively light bullets destabilize very well in tissue or obstacles. Leading to far greater wounding and decreased barrier penetration. Both of which are desirable in a defensive handgun.
Yep
>Deceased
>Sitting upright
Counterpoint: handgun JHPs at high velocity deform and fragment massively. There isn't any gel testing I can find and I'll eventually have to do it myself, but I do have a video of a 147gr XTP exploding in water jugs at 2200 FPS while still managing to keep the core intact.
16:20
5.56 works like in
because it's going so fast and shatters. 7.62 Vatnik wounds are usually shit because it's "only" moving mach 2 and can't self-destruct with FMJ, but make no mistake that it does absolute work in expanding loads. See pic related.
Again, see pic related. This is preferable in a defensive round because you have a lot of wound vectors with good penetration, which is good when you're making "accurate enough" shots for the amount of time you have to fire. Hunting rounds prioritize extreme penetration and weight retention, which allows the bullet to pass through so you don't have to go looking for a piece of lead and/or copper in your food, and makes sure you can hit exactly what you're carefully aiming at from a distance at an unexpecting target. That deer is going to be really easy to get a perfect heart or double lung hit on while he eats some grass in a field, but the dude actively shooting at you is not going to afford you any of that luxury.
>hp 762x39
Wouldn't it be better to just get a regular 762x51 since "allegedly" they behave like 556 but with double the kinetic energy?
>That deer is going to be really easy to get a perfect heart or double lung hit on while he eats some grass in a field, but the dude actively shooting at you is not going to afford you any of that luxury.
So true, it's easy to hit when the target isn't shooting back at you.
Of course .308 kicks the shit out of 7.62x39. I was replying to an example of 5.56 vs 7.62, though, which is similar in energy but much slower and fatter than 5.56.
I see, thanks.
Is there any 556 variant of the 556x45 that's more powerful, like the 762x39 to 762x51?
there are a few 22 caliber cartridges that are less powerful but very very few that are faster than .223
I guess uh like .220 Swift?
there are a few others but they're not very useful
Why the frick diddnt you say 22-250?
I didn't say 22-250 because I don't really care about weird high velocity shit like that and 220 swift is the one mentioned on wikipedia
I guess I could have started flipping through my reloading manuals
>laughs in .22-250
A .223 can do basically everything a .22-250 can while being cheaper. But for certain applications a .22-250 is better and is clearly a step up in speed. It’s been around forever
People who bring up .220 swift are noguns who googled "what is fastest bullet" and don't know what a handload is.
I do reload for my uncle's .220 since it's so hard to find ammo and it's so expensive. It's a little faster than .22-250, it does have more case capacity. However, it's not that much faster and isn't worth the extra cost and difficulty finding ammo. Even reloading for .22-250 I like the option of being able to pick up a box basically anywhere.
Also you aren't wrong but they can't even google well. That honor goes to my 2nd favorite cartridge, the .22 eargesplitten loudenboomer.
Why is it that those "super" .22 rounds are so massive compared to "normal" 4kfps+ cartridges?
>"normal" 4kfps+ cartridges?
What do you consider "normal" 4k fps cartridges? There are very few rounds that can get that fast. The ones that do are varmint rounds shooting super light bullets. Sure a .204 Ruger or .17 Rem can hit over 4k but they shoot like 24gr and 20gr bullets. A .243 can with 55gr but that's more powder and a larger case than a .22-250.
But basically it's either a lighter bullet or more powder and/or pressure. It's not magic.
Better in the same way it'd be better to use .300 Win Mag because its more powerful than 7.62.
True, 762x51 is in a higher category than 762x39
Unfortunately that seems to be a rather common thing with XTPs at higher velocities. Even tendencies to rip apart in flight. I believe Corbon had an offering of the same jhp, but used a different name. This is why I never bothered with these offerings from Underwood for my carbine. I've hear of gold dots doing the same, but from what I have read not to the same extent. People need to realize that some of these particular jhps are designed specifically for common handgun velocities and not hot or loads or being shot from longer carbine barrels.
>Unfortunately that seems to be a rather common thing with XTPs at higher velocities.
You say that like it's a bad thing. A massively expanded bullet with high fragmentation is a dream for defensive ammunition as long as it penetrates well.
>Even tendencies to rip apart in flight
You'd have to throw it REALLY fast. I shoot the 185gr XTP at 2200 FPS, which is a huge candidate for this behavior, and I have never seen it happen. XTPs are actually the least likely to do this out of pistol JHPs, but I've seen zero .45 JHPs do this at that speed.
>these particular jhps are designed specifically for common handgun velocities
Yeah, so they can perform like handgun rounds. I have never seen proper gel testing done for mach 2+ handgun JHPs, but I'm willing to bet it's similar to defensive rifle rounds.
Yes, but that requires a lot of changes not conducive to use in a pistol. You either increase OAL, decrease velocity with a longer and therefore heavier bullet, or need a longer barrel when you further neck down the case. This makes the grip harder to fit in a hand, or makes the gun much longer. A short and wide bullet it the best way to avoid all of these issues.
For a bullet designed for maximum expansion, as opposed to fragmentation, that's not necessarily a good thing. After all they are designed to expand, not fragment. It may have been Corbons DPX line. Yeah I cannot say that I have heard about.45 XTPs coming apart like this. But then again I only own one .45.
I would love to see some ballistic tests on pistol rounds traveling faster than 2000 FPS. At that point they should perform more similar to a rifle round and cause hydrostatic shock, hopefully.
Increasing the pressure is also a choice.
.30SC uses a 50kPSI chamber pressure and is completely safe with guns built for it, which is more than enough for a hot bottle necked cartridge to function with relatively short barrels as well.
There are plenty of bottle necked pistol cartridges that are comfortable in the hand. The Tokarev is probably the most common and is completely fine in average size hands. The FiveSeveN being even more so.
I am fairly of the opinion that SCHV pistols are the definite way forward for gun design.
You can apply that pro-fragmentation style of bullet design of 'rifle style' pistol projectiles as well.
No need to limit yourself.
>TFW no 50ae necked down to 5.7
Still got .440 Corbon. But it would be cool to see a .50ae necked down to .357/.380 diameter.
What I WANT is a pistol round that can hit mach three out of a barrel less than 12 inches long.
That is ALL I want and that is ALL I've ever wanted.
How is hunting performance different from defensive performance? Hunting is literally to kill the thing as fast as possible, via high penetration to reach vital organs.
Animals tend to be a lot wider than humans.
And hunting is largely about causing the least amount of damage to meat as is possible.
Penetration requirements aren't as significant with human targets. Given that even a body builder is going to be thinner front to back than a deer or a bear is side to side.
And while I'm not one to be judgemental, I don't think you intend to butcher and eat the person that you just shot.
So a lot of what you'd want to hunting, is suboptimal for defense. And vice versa.
i sketched up a .45 acp necked down to .30 caliber in 2004. they owe me royalties
It's all marketing.
But I wish there were Glock/1911 barrels and reasonably priced ammo made for it, it's the best high velocity pistol cartridge out there.
Ah well, 9x25 Dillon is only marginally worse in performance.
7.5FK = 95gr @ 2000fps in a 6in barrel
357Sig = 90gr @ 1900fps in a 4.5in barrel
Holy frick this round sucks, I thought it had "rifle-like" ballistics or some shit?
>357Sig = 90gr @ 1900fps in a 4.5in barrel
That's a pissing hot load only made by one company.
to be fair 7.5 is only made by one company last i checked. but to be fair again, i haven't checked in quite a while
The point is that you can't easily compare loads between manufacturers. You would be able to fire pissing hot boutique loads for 7.5 FK if it ever took off.
2300 FPS out of a 4″ barrel - liberty defense
With a 45gr projectile, bad at penetration but great at making massive blind holes
The same can be said about 7.5
>721 ft lbs
>25% more energy than Buffalo Bore's most powerful load
Yeah, they couldn't pay me enough to shoot that. Quickload is giving me 52700 PSI, which is 20% over max pressure in a cartridge known for being pressure sensitive. They're either selling an extremely dangerous load, or they lied and are using a 6 or 7" test barrel.
Anyone shooting a .357SIG load like that is either a liar or trying to blow up their hand.
7.5 was intended to do what 5.7 isn't great at ... penetrate body armor at distance.
and it does it. and the ammo is available to civilians...somehow... but there ya go
>the ammo is available to civilians...somehow... but there ya go
It's basically impossible to stop the proliferation of ammo that penetrates soft armor for pistols only. Soft armor is not that complicated to beat, it doesn't require any special material or trick really.
You could easily make 5.7 solid copper projectiles legally, beryllium copper isn’t on the list for prohibited bullet materials (for pistols). But there’s no market in it when people could just buy solid copper 9mm, .40, and 10mm that is better in every way to 5.7.
>beryllium copper isn’t on the list
It literally is.
Basically any metal will punch Kevlar if it's got a fine point on it and is moving over 2000fps.
I thought AP ammo in a pistol was only illegal of you have it on you "during commission of a crime". Go read the fine print. Red box and white box 5.7x28 is avaliable for anyone to buy on GB along with boutique bullets made with funky projectiles.
AP pistol ammo is illegal to buy or sell.
Luckily soft armor is beaten by all kinds of ammo that does not legally count as AP.
Is it?
Because I've not seen any compelling evidence 9mm screwdrivers can defeat soft armor. And Liberty's 50 grain bullet can, but post-penetration effects are pretty bad. 5" in ballistic gel is not even close to ideal.
Fort Scott 9mm TUI beat a level IIa and IIIA layered on top of each other out of a regular length barrel.
>post-penetration effects are pretty bad
enough penetration to hit their heart.
you're moronic, that 5" in gel will not directly translate to 5" in tissue.
You clearly have not watched a single YouTube video of people shooting IIIA body armor. IIIA is fricking junk.
?t=734
Even from a G26 you can do it with the right screwdriver. There are dozens of videos of people showing various 9mm, .357 sig, .357 mag, and 10mm going through IIIA. It's long been known 7.62 Tok can do it and these are faster. Granted a lot of those have mild steel jackets but the frontal area is reduced by a lot with the lehigh or fort scott bullets.
I've seen 3a get beaten by the extremely underpowered G2 RIP ammo. You don't even need to be particularly fast; just sharp.
Not too many people recommend 9mm XD rounds if you want to pen soft armor. It's better to go up to 10mm or 357sig if you want to play with copper solids for that purpose.
who said anything about copper solids?
>screwdriver tipzzz
>nylon rod, drilled as sabot
>.030" copper sheet superglued to the bottom of the sabot to help with the pressure
Is it illegal to handload?
Nope, just can't buy it or sell it.
I'd be careful to check whatever jurisdiction I'm in. Simple possession of AP ammo can cause significant legal complications. Not the least of which: what is the definition of AP ammo? There could be a lot of legal fees involved in settling that question (and "intent") before moving on to more complicated topics.
Search youtube. There's a bunch of videos of people loading insane things into to shotguns just to see if it will shoot at all. Some of the penetration tests reveal highly intriguing avenues for further research, as well as failures that aren't necessary to repeat.
>what is the definition of "ap?"
>picrel for the glowies
If you read the atf framework for AP exwmptions pdf, they immediately conflate "larger than .22caliber" to mean that the only ".22cal" is .22rimfire. Which is bullshit. So you'd be perfectly legal shooting a 4.6x30mm firing handgun, even with solid tungsten carbide projectile, as its approximately .17caliber. Of course they would have a problem with it because they'd cry its not .22rimfire so it can't be legal. As far as projectile designs go, a sabot shooting a chunk of ultrahard ceramic is going to be fully legal and capable of punching through quite a bit. One could experiment with a chunk of hardened nickel-copper welding rod behind a small ceramic ball bearing or a piece of fake diamond. You could also just use pure tungsten, as it is "alloys of" tungsten that are b&, going strictly by the language of federal law. A piece of tungsten shot could give a plastic sabot containing a piece of ceramic sufficient mass to retain some energy at reasonable pistol range as well. Fort scott copper solids could be drilled out to decrease their mass, and the extra empty space filled with powder, like the subgun THV loading was. Lots of ways to skin a cat.
>So you'd be perfectly legal shooting a 4.6x30mm firing handgun, even with solid tungsten carbide projectile, as its approximately .17caliber.
No. The part of the definition that restricts specific materials (arguably including tungsten carbide under "tungsten alloys") makes no mention of caliber.
Caliber only comes into play in the second part of the definition, regarding jacketed bullets where the jacket is over 25% of the total weight.
You're right about the caliber part. But I fail to see how pure tungsten would be banned, as its not an "alloy of." Under .22cal could let you run a jacket greater than 25% of the projectile weight though. Not sure what good that would be over just a monolithic projectile at that point.
>picrel, m39/B projectile
Anyone have the capability to drill/lathe out a fort scott tui something like this cross section and post pics and weight in grains? Could use a piece of tungsten shot to increase mass at the front, and end up with a large hollow base that could be powder filled.
I might weigh a few different bit drivers later and post results later for shits and gigs. Bodies lookin like they got dragged through a construction zone lmao
The post said tungsten carbide, which is neither pure tungsten not an alloy of anything -- it's a composite with grains of WC ceramic in a metal (usually cobalt) matrix.
But either way, I think as long as ATF's doing the interpreting, the finer points of material science will be very deliberately ignored.
oh i know 😀
do you like the Five-seveN? i thought about buying one just cause i own a PS90 but i already got a walther.
The Ruger 57 is generally a superior 5.7mm pistol. Cheaper, too.
even with the new Five-Seven model?
Hell yes. FN always over charges and underdelivers.
The ruger has a half-wienered hammer thing where it has a trigger pull like a double action but will only let the hammer fall once like a single action
It's not bad
>visible S/N

No it wasn't moron. It's a game pistol for Euros who have to frick about with paperwork. That's why its stock config is advertised on its site taking down "big" Euro game.
>"big" euro game
so, roaches?
It was designed for military contractors that wanted a gun to give them 7.62x39 performance at 100 yards.
>liberty defense steps in
2600 fps would be my prediction
Nice 556 speed.
I wish I could get 9mm liberty defense ammo here, must be fun to see the craters it make in meat targets, even if it costs penetration, imagine the superficial damage it would cause, 2 shots in the same area would be massive.
>I wish I could get 9mm liberty defense ammo here, must be fun to see the craters it make in meat targets, even if it costs penetration, imagine the superficial damage it would cause
Liberty XD ammo does not cost penetration. You're getting around 18" which is the standard.
I don't believe he was referring to their Monolithic ammunition.
I meant their hollowpoint ammo.
It's a pretty pointless round other than a novelty. The only "hot" man stopper people should be carrying is 357 Sig.
I don't know if there are any statistics for it, but I'm thinking it would be good for bear defense.
Also, given it's armor pen capacity it's good if you're in a position where you expect to have to deal with attackers that may be armored (a niche role, yes, but it does exist for folks like armored car drivers and other folks who are essentially couriers for very valuable things).
Any handgun round down to .22lr seems to be effective against bear. The only time documented times the bear wins vs a gun is because of unwillingness of the victims to shoot the bear.
https://www.ammoland.com/2021/06/handgun-or-pistol-against-bear-attacks-104-cases-97-effective/#axzz7aue9OtzX
I’m not going to run around bear country with a .22, but, as always, having any gun is better than no gun.
>The only "hot" man stopper people should be carrying is 357 Sig.
the only reason you believe this is because of that church shooting.
Son. I've been carrying that round since 2013.
>he thinks there is an appreciable difference between 9mm, .40, .45 and going ujp to .357 Sig
>he also thinks .357 mag and 10mm aren't worthwhile carry options
You can't have both.
It's perfect for a modern OHWS. Instead of asking a sniper to carry his heavy .330+ ish caliber rifle and then also a fat pig Spear on his back as a backup, why not issue him a big handgun? We've come a long way since the Mark 23 and it isn't trying to make poor old slow .45 do the job that a rifle was meant to do.
All pistol rounds are categorically the same.
Weak bait. But here's a (you). Now frick off.
here you can one too
25ACP is categorically the same as 10mm
>all the militaries uses 9mm just because!
It's because pistols DON'T MATTER
They are merely tools of convenience.
I don't agree with that but you can't tell me a modern double stack with a really hot .25 ACP isn't intriguing. Might be because I'm a .32 gay and wish there were modern, non-pocket pistols for it. But if you had a subcompact or compact sized pistol in basically a .25ACP +P+ you could have 20-30 rounds in a small gun. Sure it's marginally better than a .22LR from a full length rifle, but that doesn't suck either
I just want that euro-only double stack compact .380 glock. Add a extended bbl and carry comp, boom perfect self deense weapon for old folks.
>hurr
>durr
Europe has moose, deer, and wild pigs. Unless you really expect me to believe that the average NA hunter is hunting brown bear every season (hunting bears is very expensive), the size of game is very comparable. The *amount* of game is much less tho.
>.25ACP +P+
I'm intrigued, but automatically assume there will be hundreds (or thousands) of .25 autos blow up in the hands of the people shooting them. It would, sadly, probably need to be addressed by making a .25 +P+ cartridge a size that can't feed into a normal .25. Because morons. And we're just not allowed to have Nice Things™.
I'd love a boot .25 with about a 2" barrel and 12 or 15 shot magazine rated for +P+. Gotta believe it would be loud, but very curious as to just how loud.
Don’t you just heck in love science bros
>based opinion on idiot coroners instead of results in the field on living targets
Only really between the slow and heavy 1900s cartridges.
Bottlenecked cartridges and faster and lighter weight modern chamberings are far different.
You know kid back in my day
It looks like the gun is welded to its holster.
>holster
Thats no holster
Really wish the swedes had tried more stuff with 6.5 CBJ. The tungsten sabot shit was so cool.
This is very interesting. I’m wondering if that ammo (based on a 9mm sabot holding a 4mm projectile) could simply be used in a typical 9mm handgun. But then again, even going 2700fps, how much damage can that little bullet do? I’d have to be convinced. A 5.56mm can do plenty with 55grains… but how much does this much smaller projectile weigh? Inquiring minds want to know. What is the foot pounds of energy at the muzzle?
Nah you got it man. Just get a 10mm
Does the PSD really weigh three pounds
10mm is the hardest hitting round you can/should stuff into an semiauto handgun. Anything more powerful and you should design a revolver to handle it. The FK shows that yes indeed you CAN create a harder hitting handgun round, but you SHOULDN'T because the thing is too big to be practical as a handgun. It's just a meme like a Deagle, not a real practical gun whereas 10mm can be had in practical size/weight and manageable recoil (for straight men). There's also no need to go above it, 10mm can kill a bear with ease and decent shot placement, this FK thing was designed to be a sniper rifle "offensive handgun." Totally moronic concept, handgun is a backup or emergency gun.
Its longer and taller than a Glock 20, but is narrower.
If you're already going all out on getting the most powerful handgun possible, the move to the FK BRNO provided your ammo budget is generous, isn't a huge step.
It’s also a full pound heavier than the G20. A 3lb pistol when empty is kinda ridiculous. A full sized steel 1911 is 7oz less
>He's never owned a 12lb bullpup
NGMI
The pullbup aren't that bad because the balance means most of the weight is supported by your core; not your arm. It's also not as far from your body, so leverage is on your side.
>he has a bullpup pistol
I honestly want to see a 12lb bullpup pistol
It's not a pistol friendo.
Yeah no shit. But I was clearly talking about pistols so why are you bringing up bullpup rifles.
>Muh 7.5 FK
>Muh 9x25 Dillon
10mm Auto exists. That makes all that gucci shit completely irrelevant since their slight performance plus doesn't justify the massively increased price per round, the virtually nonexistent factory guns, the extremely reduced choice for rounds, bullet weights and -variants.
Deal with it: Such rounds are for snoflake dudes who don't shoot enough and really think a fricking 10mm Auto ain't more than enough.
Don't get me wrong: These rounds are awesome and they have their niche. But please don't act as if they were a needed alternative for daily carrying and sd-situations.
Nobody needs gucci rounds when 10mm exists, period
fast bullet funny
Based chosen caliber wielders
The more time I spend on /k/ the more I think I should trade my Glock 30SF for a 29SF
Does nobody make a conversion barrel? If I recall the frames and slides are largely the same.
Maybe you're built different but I'm 5'9 and average build and while I certainly could fire my G29 Gen 4 okay, I wouldn't say that I have anywhere near the grip security/stability that I have with my g17c. My rapid fire was pulp fiction revolver bad lol. Although it was certainly cool to see that you no shit really can fire 40 Smith & Wesson in it without a conversion barrel. Although now that I think about it, my friend had some intermittent extractor problems when he put a 9mm Barrel in his gen 3 40 cal, and if you plan to shoot 40 Smith & Wesson then you could have issues as that headspaces off of the extractor in a 10mm barrel.
Overall I would say I really did enjoy 10 mm as the versatility is just unmatched. It's unfortunate that nobody makes heavy subsonic rounds as I'm pretty sure you can fit a 230 grain projectile in and the sectional density would make it a superior choice to 45 acp.
If you’re in the game for penetration, 9x25 and 7.5FK have better cross sectional densities (9x25 depends on selection but the only two options for 7.5FK blow away 10mm).
Dude, let's be a tad bit realistic here. You're right, sure. But then: People in Alaska carry 10mm to fight off moose and other XXL game.
Is there honestly a good reason to accept all the drawbacks of 9x25 and 7.5 FK if 10mm does the trick even when a fricking grizzly attacks you?
I mean yeah, more power's always better. But if you got already a round that can kill most animals on earth, why would you carry an even stronger one which is much more expensive and has other drawbacks too?
Kevlar penetration
Meh. I'd rather train to aim for the head or the area below the belly button. But that's just me.
Some people are like that, 10mm is perfectly adequate and can be found in high capacity, reliable, guns. That doesn’t stop people from carrying .44 magnums that are larger than a Glock 20, hold half as many rounds, or even carry single action revolvers in .44 mag or .45 Colt / .454 Casual. Or people thinking bigger is better and shooting .45 Super or .451 Detonics or other .45 ACP based magnums (these rounds have worse cross sectional density that 10mm across the board, .45 ACP projectiles are not designed for this velocity).
i went down the rabbit hole of studying different calibers and I think the moose and bear thing with 10mm is a meme more than reality. first of all you wouldn't want to shoot a bear to begin with. you would want to get the frick away from it if possible. with all of my research the only thing I'd want to defend myself from a bear is a 9mm pistol with an extended clip, using full metal jackets.
>defend myself from a bear is a 9mm pistol with an extended clip, using full metal jackets
A very reasonable and sensible option. I personally would call that the minimum I'd comfortably feel I would escape the situation with no or minimal injuries. My innawoods backpack & camping carry is an old S&W 5906 with 17+1 in it and two spare 17 round mags. One of the spare mags is JHP, everything else is FMJ, all 124 grain (I decided that's the only weight I would ever shoot, for Reasons, so I'm standardized on it).
>Revolutionary new cartridge that blows all that old shit out of the water
Yeah, when you get a little older you'll notice that such a round gets invented every few years. Most of them fade away real quick because they don't offer a significant advantage aside from more power.
>Revolutionary new cartridge
is it faster than 2,200 feet per second?
does it cause hydrostatic shock?
at least with .45 gap you could use 90% of the reloading components and equipment you already had. Just need new brass, you can still use all of your dies and even bullets. afaik you could even trim down 45 acp brass.
but this is definitely just a cash grab.
>Revolutionary
homie that kind of design is older than you.
It's just a marketing ploy, exactly like 5.7
You have to buy their fancy pants looking gun (which is just a CZ derived design)
Then you have to buy their expensive ass ammo that only they sell.
So they get your money upfront with the purchase and continue getting money because you are expending their ammo.
But then they didn't make anything else that used their cartridge and only recently rumored to be making a compact, so they made some conversion kits for more common calibers.
Tell me anon, what other pistol round goes through IIIA vests like 5.7 does?
Not him, but if you’d bother to read this thread you’d have plenty of examples. Even with videos. Even 9mm with the right bullets, being Lehigh 68gr xtreme defenders or fort Scott 80gr TUI, can. Obviously .357 sig and 9x25 Dillon can since they can use the same bullets going faster. 10mm can with multiple all copper bullets. 7.62 tok has been known to beat IIIA for decades and still does. You don’t see it used or tested nearly as much but .357 with those same types of bullets could do it too. It can push the same diameter bullets faster than 9mm or .357 sig depending on barrel length. It’s really not that rare to beat IIIA
Fort Scott TUI 9mm out of a fricking P365 (3.1 inch barrel). Sporting (hollow point, the vast majority of 5.7 available) 5.7mm literally cannot pen IIIA without a 16 inch barrel.
