There are factors than just penetration depth. Overall energy, temporary and permanent wound cavities. The 10mm ammo was also the watered down version to try to get the appearance of comparable penetration. Full power 10mm would show greater impact to the gellow and larger wound cavities, maybe deeper penetration.

Anon asked about bears, for which you'd be worried about penetration and not the wound channel size beyond the size of the bullet itself.
On the other hand, if you want that sort of velocity (begins around 1500-1600 fps for a bullet with the frontal area of a 10mm) there are plenty of loads ranging from 155gr xtp bullets at around 1500 out of a 4.6" barrel to the wizz bang civilization defense stuff making 2400 with ultralights.
The underwood screwdrivers are nasty in this caliber as well.
I'm not arguing for 10mm, it's a pretty silly round compared to 9 or 40, but there are no shortage of offerings in it that will exceed the elastic limit of tissue.
>>
>>65125967
My grandfather told me that people who prefer a .45 ACP over a 9mm are like people who own lifted pickup trucks with no dirt or debris on it, "they are always trying to compensate for something". 9mm and small pistols are good for the average person and can carry more in a mag than a larger round.

>>65126563
I read a study on it a long time ago, and don't have it on hand. I remember that with 357 mag it was observed beginning at around 1500 fps, and obviously gets better the faster you go.
It went how you'd think, smaller diameter or sharper projectiles that don't fragment have to be going faster to exceed that elastic limit than things with larger frontal area.
Stuff like those liberty rounds will blow horrible meat grapefruits out of tissue when chambered in stuff like 357sig or 10mm, other hot offerings like various underwood stuff will do it to a lesser degree but still manage to break out of the pistol curse of "only pokes caliber sized hole" for whatever it's worth to you.

According to Tim Sundles (founder of Buffalo Bore ammunition and a very experienced dangerous game hunter), spicy .45 ACP with a properly selected projectile is preferable to 10mm for animal defense. Unless your barrel length is enormous, you aren’t getting anything like rifle performance from an autoloading handgun round. Your priority should therefore be reaching sufficient penetration depth with a large projectile diameter. By these parameters, .45 caliber beats 10mm even without getting into the really hot stuff like Super/SMC or Rowland.

>>65126229
If you’re worried about bears, carry bear spray. Handcannons are statistically inferior
>>
>>65126737
I should clarify that, while 10mm does have better sectional density and penetration than .45 options, hardcast and monolithic loads in both chamberings always demonstrate SUFFICIENT penetration for realistic animal defense scenarios. “Energy dump” has never been demonstrated to be anything other than a sometimes-useful abstraction, and you aren’t going to be getting some kind of magical turbo inelastic hydrostatic blast effect out of your 4.5”-6” barreled autoloading handgun on tough big animal tissues. The wider hole through the animal, therefore, wins the comparison.

Great choice if you want to shoot through barriers better than 9mm using a handgun without giving up too much capacity, I guess, but it seems kinda overrated otherwise. .40 S&W is worse, at least…

You know, discussion of bear defense is way overstated for how much of a threat bears really are. In black bear country (everywhere in the CONUS except the Idaho panhandle and surrounding areas) I feel completely secure with a pocket 9 or .380. I don't really buy the "bears are a le heckin euphemism for niggos lolololol" thing either because this is 4chan and you can just say nigger. Besides, even the most zooted nog completely disassociated on the latest Chinese synthetic drugs doesn't suddenly gain a bear sized torso that needs 32" of penetration.

But yes 45 super can be somewhat better than 10mm (if you have a gun properly suited for it). I do actually buy both 45 super and 10mm, but I buy it from Underwood when they have sales, with the added bonus that they've never killed people's dogs while trying to poison wolves

2/2
The loads I entered into GRT exceed the 28k PSI "limit", because that limit only has non-fully supported chambers in mind. You can shoot .45 Super in a normal G21 at 28k PSI or less with a 22# or 24# recoil spring. The "hotrod" loads as I've seen them called in picrel is where you need to fully supported chamber like KKM or LWA barrels.
A USP stock can handle 28k PSI .45 Super loads, but idk about the hotrod loads going in the USP. Or M&P 45 w/ a heavy recoil spring for that matter.

I'll be posting my recent .45 Super loads and specs in reloading general soon if anyone wants to check it out.
>>
>>65126748
I like spray, because you can use it when a bear is being a nuisance or an asshole and you're not sure if it actually wants to fuck you up. In that sense it is great.

If a bear has already made contact with you or someone else, I'm not going for bear spray.

Sundles recommends plain old .45 ACP +p. He actually has a video complaining that his Supers doesn’t reliably work in his USPs. He also sells 10mm. If he poisons wolves and dogs, I think that’s a chickenshit move and I’m not a fan of it, but the guy knows ammunition.

I hate these retards with their rigged cope test, example of lying with statistics or through omission. Simply put, a bigger heavier bullet going faster kills better. Anyone trying to tell you otherwise is blowing smoke up your ass.

10mm is good because its at the intersection between power, capacity and just manageable enough recoil to still be usable. Enough power to take most large game and defend against bears. Will shoot through cover and make assholes with soft armor think twice, high velocity and good sectional density means it remains fairly effective out to longer ranges. With a similar magazine capacity to 9mm, usually the same or a bullet less.

If your out in a rural area with large herbivores, bears and methed out redknecks in trucks, 10mm is a good option. Of course a rifle is always better, but its the tool you have on you at the time that matters, not the one that got left at home or in the truck.

Fuck that lying nigger.
He sold me flat nose .45 that turned out to be a filled hollow point, and expanded when I shot it into gel.

I followed up multiple times after this, and he never got back to me, offered a refund, or even apologized.
And I pulled a bullet and cut it in half. It was 110% a filled hollow point.

I never see 10mm loaded that much higher than .40. I think the real issue is people underestimate .40. There's only a 3mm difference in case length. You're only able to squeeze 200-300 more fps out when you go to 10mm with a fully supported chamber and fuckoff bear rounds. That does seem to be considerable though. 10mm seems to be the furthest you can push a semiauto handgun round before it just becomes unviable due to excessive recoil or size.

Brother you've never even seen a grizzly bear. All these esoteric fuddlore "formulas" can suck my balls, they aren't scientific and exist nowhere in actual physics. The TKO factor in particular is maladapted to literally every kind of hunting besides elephant hunting, the whole premise was that a shot that missed the brain could still knock the elephant out. Are you making a lot of missed brain shots on North American game?

Furthermore, bullets are way more important than cartridges. I would hunt the biggest chad 7pt elk with a .243 loaded with 100gr partitions with no hesitation; I would not do so with my .30-06 loaded with 155gr ELD-M, which delivers double the KO factor.

Its 2015+11, ye olde elephant hunters of olde were highly based but if we want to see if a round is good or not we can just shoot gel and measure it. Spare the hocus pocus and just show me the fucking hole it makes.

If you got caught you shooting at elk with a .243, every one of the game wardens, guides, hunters, and woodsmen up here would beat your ass silly with your own shit and throw it in the river after you started crying. Your mother obviously still picks out your clothes for the day.
