45 ACP vs 10mm

Irish B · January 30, 2013, 12:44 AM

I not long ago bought a 10mm and bought my brother a .45 ACP. We've done multiple side by side tests on objects to see which is the "better" caliber. Obviously the 10mm penetrates deeper but the .45 creates a larger diameter wound channel. Which is the better cartridge for two legged predators? The reason I bought a 10mm is because I have a very large bear problem where I live but also I wanted a very effective HD gun. Thoughts?

Either caliber will leave a two legged predator wishing they had stayed at home.

They're both great calibers. You can't go wrong with either. I personally prefer a 10mm though it costs a little more to feed.

Bear never broke in to my home so 45 good for me . I think 10 be good gun for bear Might be hard to train then to shoot it. But bet it keep down number of human tresspassing in their homes

try shooting both without hearing protection as you might during defense situation. 10mm is pretty loud.

Hard cast 10mm 200 gr will do better against a bear vs a standard 45 ACP.

The 45 super effectively levels the playing field, if you have a 45acp platform that can handle it. Both the 45acp and 10mm are excellent but if you're in grizzly country with a handgun, I'd suggest a .454 at minumum.

On paper I think the 10mm wins out.
On it's way through a person I doubt the recipient is going to notice a difference.

My own preference is for .45 as I tend to be able to get a follow up shot off faster. But 10mm is far better against bears, so for a duel purpose gun I'd say you made the right choice.

I prefer 10mm, but as someone else noted, it is loud.

Although I have both calibers, The 10 is my favorite!

Carried them both, competed IPSC with both. There are some mighty powerful 45acp +P rounds that might be a real world equalizer between the two calibers. I have tested the Gold Dot 200jhp +P and it is mighty impressive. I dont think you can go wrong with either.
