Using a powerful subsonic caliber with a scope, suppressor, and offset close range optic, such as a red dot optic, it is possible to shoot accurately and quietly at close range and even at 1,000 yards. Using a battle rifle caliber, a single rifleman can perform precise, suppressed long range shooting as standard practice or accurate close range shooting with the same rifle and caliber, even in burst fire.
Nothing subsonic is going 1000 yards.
Subsonics can easily reach 1000 yards. Actually subsonic .300 blackout would have more energy at 1000 yards then supersonic .300.
Only you have rainbow trajectory and need for range finder with 1 meter accuracy to hit things with subsonics at those ranges.
Yeah contrary to all the other anons replying to you I don't think many of them have ever checked velocity graphs for subsonics at distance, it actually doesn't drop very quickly at all. The primary issue with supers is the transsonic transition, when something purely ballistic drops back through the sound barrier that will completely frick accuracy in inherently chaotic fashion.
Having said that, hitting anything IRL with subs at that range is going to be very hard, particularly if it's moving and/or there are weird winds or other factors. Armor pen is going to be crap as well. It's not really a thing for a reason.
This guy couldn't make it happen at least not with a short barrel:
Theres tons of video of this guy making long range precision hits out to like a mile or more and there is even a video of him shooting an 11.5" SR15 out to around 710m. He can get it done, it's just not practical with .300subs or at least it wasn't with that barrel under those atmospherics on that day.
>300subs
I don't think a bigger round would actually help much, based on looking at 375, 450 and so on. Drop is primarily a function of velocity, heavier stuff will of course have more energy if it hits, but the drop is real similar.
The only thing I could imagine that theoretically might make subsonic work at more distance would be a smooth bore discarding sabot where the bullets were actual lifting bodies, which at least would be technically feasible with modern CNC and copper. Then the bullets would no longer be following a classic ballistic trajectory but would actually be [flying](gliding), with the forward motion actually generating lift.
Tons of challenges there though. You've now got an asymmetric projectile, so suddenly orientation of bullet and gun matters. It could self stabilize a few degrees no problem, but if you fire it sideways or upside down it won't work. So you need to deal with that somehow. All the challenges of sabots of course too, though we can do that precisely enough nowadays. POI would become significantly more complex to predict.
Sure would be cool to see someone give it a shot though. I'd love to just see what happened, even with a pure bench setup
>have to aim at your target at 5x with the bottom of the scope (assuming you have a scope big enough to even aim that low)
>bullets take 5 seconds to hit their target and they are traveling downwards at a 45-degree angle
this is not feasible.
>subsonic caliber
You fricking what
>quietly
Stop getting your gun knowledge from Hollywood
>even at 1,000 yards
You're fricking moronic for suggesting it's feasible to shoot a bullet like a mortar and hit a target
>battle rifle caliber
>quietly
You have never shot a gun
> even in burst fire
>quietly
>accurately
Why do ESL morons ask such stupid shit. Post your guns along with a time stamp or frick off 3rd worlder. have a nice day either way.
>subsonic caliber
Noguns detected

Scope with variable parallax is always useful beyond 100m
Supersonic is the way. If you're planning on doing some CQB or trying to assassinate a group of people, then you want to be carrying both subs and supers. Also, you need 300 blackout.
.300blk sucks
.45 is better subsonically and 7.62x39 is better supersonically.
300 blackout is a rifle cartridge. Supersonic performance is more important than subsonic performance. I have a 7-inch 300 blackout upper, and each shot has the same muzzle energy as an M855 round coming out of a 10.5-inch barrel. It's just that it's not as good at penetrating armor or walls as the M855 10.5-inch barrel.
I love the look of a short AR but boy do I hate the performance. Unless you're doing CQB, anything less than 16" is ass.
>I love the look of a short AR but boy do I hate the performance.
They're still rifles, anon. The performance difference between shorty rifles and pistol caliber carbines is night and day. My 7-inch 300 blackout, which has the same muzzle energy as a 10.5-inch M855, can make bottles and cans literally explode, while shooting the same things with a pistol caliber carbine will only make a small hole at the front with a medium sized exit hole.
You must be over 18 to post here.
>1,000 yards
Not practically. You are delusional, just like every other
>imma be illeet supersniper with my 8.6!
moron
You'll need 150 MOA of adjustment on your scope if you zero at 100 yards.
Best of all, a range estimation error of 1 yard (1/1000th error) will make you miss by 3.5 inches.
No, the best bit is that a 1mph crosswind will deflect it by approx 37MOA.
These nogunz threads. Wow.
And the bullet would just bounce off the target.
>1200 joules
>bounce off the target.
A subsonic round after travelling a thousand yards?
Are you blind?
that is right 1200 joules baby.
Its just people are not accustomed with subsonic ballistics. Below supersonic drag drops drastically. Heavy subsonic bullets barely lose any velocity.
>Its just people are not accustomed with subsonic ballistics. Below supersonic drag drops drastically. Heavy subsonic bullets barely lose any velocity.
like earlier anons said too most people only shoot supers and going back down through transonic definitely does frick things up. so they may think of "subsonic" as a danger zone in which bullets don't work well but not realize its the transition not starting there. also people only shooting supers may not have the barrel twist needed to properly stabilize subs. like, 308 subs do exist. but you need a 1:8 twist usually and that's not the standard 308 barrel.
The bottleneck in their practical performance isn’t terminal effect, it’s their shit trajectory. Energy at 1000yards doesn’t matter if you can’t hit shit that far anyways.
>powerful
>subsonic
You must be 18, you have to do back
OP is a homosexual but at more reasonable distances subs can do ok. Like even at 200yd a decent 395gr 450 bushmaster sub will still have around 750 ftlb. That's around the same or more as standard 55gr 5.56 at the same range, though it'll cause a much bigger wound. Has vastly more drop even there and falls real fast after that, by 300yd you're talking like 100+" of drop which is silly. But at <200yd that's plenty enough juice to frick stuff up, I'd call it a "powerful subsonic round", with the implication of "powerful for a sub, and plenty enough to be effective".
Unrelated but if I were to pick up my first suppressor would it be better to get a .308 one or a multi caliber big bore compatible pistol compatible one and a threaded 1911 barrel?
What are you shooting? That said, single caliber focused is always >>>> jack of all trades, and pistol suppressors typically do badly with rifle rounds. If you're shooting 30cal get a 30cal can. If shooting 5.56 in particular (which doesn't suppress well) get a proper focused can. You're better off sucking it up and getting a few caliber specific ones, everyone at least considers like you "man getting cans is such a pain, what if I just got one that did it all!" but then you'll find you really just want to leave a couple of good ones on your favorite guns.
Don't forget to consider your operating platform too. If it's a pistol then a pistol can and whatever. But if it's a rifle does it have an AGB? How sensitive is it? Cans vary massively in back pressure.
1000 yards is wayyyyyy too far for a subsonic cartridge. subs don’t slow down too much on account of their usually high sectional density and low drag by virtue of low velocity. Even if we assume an infinite BC with no deceleration at all, that’s still minimum 3 seconds flight time = ~44 METERS drop, and 3 full seconds of being blown around by the wind. You essentially need to have a perfect wind reading at all ranges between you and your target, a perfect rangefinder with no error, the size of your powder charge down to the 1/100th of a grain, your BC to like 3 significant digits, barrel temp, etc, or else you’re gonna miss at that range.
>subsonic at 1000 yards
post one fricking gun dipshit. why are the dumbest fricking spearchucking gorilla morons drawn to suppressors and subsonic rounds like israelites to pennies
you can think je- hollywood. Same reason why suppressors are NFA and banned in several states.
actually this thread makes me think it'd be kind of a fun party game next time we're out on blm land with a dozen for shooting and bbq to bring a couple of 300s or 450s and set up some 20' tarp target at 1000yd and everyone can see if they can fricking hit it and how close lol, trying to waterfall in bullets at 45deg angle or whatever it is at that range. most are pretty good at math, one is old ex arty, it'd be pretty much indirect fire at that point like a mortar. might be fun ass challenge and change of flavor vs the typical.
but yeah lol@1000YD LE SILENT SNIPER
Stupid people have stupid ideas and like stupid things.
