10mm

Does 10mm live up to its reputation as a magic one shot stop caliber or is it just overhyped?

    .45 ACP has poor penetration and holds less rounds in comparison

      Not magic, but definately one deviation more powerful than 10mm in certain loads. Factory rounds are slightly spicier .40, which is still better than 9mm but not by much.

      Also a spicier round on +P/Super configurations, but nearly as equal on factory ones.

      10mm is God's caliber, because it was made as an advancement but was stopped because of effeminate men and women.

        Between .380 ACP (for low recoil and suppression), .30 Super Carry (for comparable performance to 9mm with more round capacity), 10mm (for power and capacity), and .45 ACP (for power and suppression), there is no need for 9mm.
        It's only a behemoth because of NATO standardization. Get it removed from that and it would improve demand for everything else and prices would go down for other rounds due to better 'economies of scale'.

    good round, makes me happy
    i prefer to carry it over 9mm for daily use
    i think general opinion has sort of gotten it backwards, at least in this part of the country without grizzlies
    if i’m walking around a long long time in the woods i’d rather have a 9mm with lighter ammo, more rounds in one magazine (since I probably don’t want to carry two), all the best OWB duty retention holsters are for 9mm guns
    but if i’m just out and about the chance i need to shoot through a barrier like a car door etc is higher, i don’t mind the weight as much bc i’m probably driving and not walking as much, so i can carry two magazines as well.
    that’s my two cents

          .40 S&W nerd here, with modern propellants you can hotrod .40 to original 10mm specs. Picked up a Styer m40a1 specifically to play with reloads since they are stupidly overbuilt and have much better chamber support than the glock 23 I usually carry. 9.6-9.8 grains of VV 3n38 will push a 180gr hardcast to +/- 1200fps out of a glock 23 depending on humidity and ambient air pressure, while staying in safe pressure range. In personal experience I had a few bulged cases with the old 3rd gen glock, nothing like that since switching to the styer. Hoping to work up a 1300fps compressed load, will probably build a firing sled just in case I get a KB. Love that magnum performance out of a compact.

            Yeah, based on my math and the calculations other people have done, I'm at about 90-92% absolute max load. I'm reaching a point where incomplete powder burn in barrel length starts becoming an issue. I can obviously go faster with a lighter bullet, but I want to stick with 180 gr because I like beeg boolit. If I cross 1300 fps at 180gr, I will post load data so other anons can replicate.

              That's getting into "need a comp" territory so you may as well go with an extra inch of barrel and retain reliability. A marginally more powerful shot isn't much good if the next one doesn't feed.

                You're going to start outrunning the mag spring, the long slides and comps slow down the action.
                Doubling up the spring will help up to a point but if you develop a borderline-functional stunt load in the Steyr it's going to choke your G23.

                Also worth bearing in mind if you're going right up to the bleeding edge you're going to have to start doing things like check every individual case for capacity, run your bullets through a sizer, and work up a new load when you start on a new batch of powder. Take out the safety margin and you're going to need to eliminate tolerances.

    10mm, or .40 Largo as many firearms experts prefer to call the round, was an attempt to improve on .40 S&W, which itself was created to satify exhaustive FBI standards following the North Hollywood shootout, where .38 Special and 9mm were found to be woefully underpowered. 10mm cases are notoriously weak, since elongation of .40 S&W cases resulted in excessive thinning of the case wall. This has caused numerous explosive failures, especially in 1911 type pistols that suffer from unsupported chambers, unlike the Glocks that were designed specifically for use with .40 S&W and later 10mm. As a result, most commercially available 10mm cartridges are underloaded to protect people that insist on using modern cartridges in antiquated designs, and the cartridge consistently underperforms the .40 S&W parent cartridge. It is mostly regarded as being a mildy spicy 9mm, and has fallen into the category of novelty cartridge. Hope this was helpful!

      Some call of duty kid is gonna read this and take it as gospel, well done. For anyone interested in the truth, 10mm was designed in 1983 whereas .40 S&W is from 1990. .40S&W is the child case of 10mm, and was derived from the cartridge in response to Feds with weak wrists and poor weapons handling skills.

    YES. 10mm Auto is frankly underrated on what it can do, 9mm is cope and .45ACP is antiquated technology. .40S&W was a marketing gimmick to put 10mm into 9mm frame pistols, an attempt for concealment and recoil control for reduced training requirements which is a HORRIBLE metric to base a weapon on.

    One shot stops with typical handgun calibers, including 10mm, are a myth. Yes it's dramatically overhyped but it does have more power. The fallacy is that that extra power matters in humans--it doesn't. When combined with penetrating projectiles however it is significantly more effective than 9mm, .40 or .45 for animals with thick bones.

    However most people don't use it for that. They're expecting to use it on people where that power is wasted.

    It absolutely has merit when extra barrier penetration and penetration in large animals is required. It goes through bear skulls and windshields quite well while still having enough mass, diameter and momentum to frick up some internal organs. Smaller rounds may do the same thing if the angles are right and the placement is good but a 10mm does it much more confidently. It also comes in a package that is smaller and lighter than a .44mag revolver. People forget that the packaging of the round, meaning the gun, matters.

    There are 2 main drawbacks to 10mm. 1. It comes in the same size frame/gun as .45acp which is thick and heavy for an EDC gun. I would not use 10mm as a substitute for a compact or subcompact 9mm as the 9mm is way comfier to have on you. Secondly, you need to buy the good ammo to get the benefit of 10mm. That means Underwood or Buffalo Bore, to name a couple. Much off the shelf 10mm is loaded to .45acp specs so as to not crack the frame on someones old Delta Elite and for general liability reasons from the manufacturer. A Glock can handle Underwood just fine.

    So, it's too big for EDC and you have to get the expensive ammo to take advantage of it. It's not as powerful as .44mag but you get more rounds in a smaller gun. 10mm is my choice for area with bear and occasionally winter carry under heavier clothing.

    I would recommend against 10mm as a first gun or for novice shooters for whom a compact 9mm is far more ideal or even a .357mag if an option with more penetration is desired.

Then there's the people on glocktalk sending 300gr bullets faster than that and 185gr bullets faster than the hottest 180gr 357 loads which makes 10mm seem even weaker

        45 acp is to 45 super how 10mm is to what redditors think 10mm is
        45 acp factory hollow point loads expand bigger for the same penetration as factory 10mm hollow points
        45 continues to mog as you increase pressures to the point of needing stronger recoil springs and/or compensators (like you'd want if you were gonna shoot a bunch of really hot 10mm)
        HK's 45s will handle really hot 45 right out of the box without modification. 230gr at 1200fps out of a stock USP45 is max comfy and will make you wonder why anyone would want a 10mm. Regular 45 acp brass will hold up to 40 ksi in a well supported chamber so for saner loads you don't even need expensive brass.

          Whatever you say, Bubba. I will say that if .45 shills got the hotter loads more popular, then I would kneel.
