Never shot a 10mm, but did shoot a 45 for awhile, even in practice qualifications.... I found it very accurate, and controllable with 230 ball...shot a practice qual with a 300 score. I ended up giving it to my son when he moved to Texas....

you are putting hand guns against hand guns and they are all sort of the same weak but much easier to carry and never your first option

there is a different guy who does some different testing , he puts 44mag against 10mm because again even a magnum doesn't carry enough more to make a big difference

rounds on target once you get into 357, 40, 10 , 45acp , 45lc ,44mag really even 9mm in some cases is much more important than foot pounds of energy
what can you shoot faster on target , what can you bring to bear faster
this guy likes the 10mm because it gets into the penetration range you want , comes in a simple , reliable package and gets rounds on target.

Hypothetically, if you jam the barrel of Semi automatic against a bear and pull the trigger that's your last shot, a revolver would keep running.

At some point the discussion just becomes "carry what you're comfortable with" and that's probably the best choice. I just couldn't seem to understand the current infatuation with 10mm over a .45, I think it's mostly marketing.

I think it is largely rounds in mag more is more better at least in people mind
not reloading does make more hits faster , will you have time for more hits , maybe but if you don't have more ammo you can't make them

also it is the marketing push so it is in peoples minds , got to do something new to sell


but also Henry and Marlin have released 10mm lever guns in trapper carbines
10mm is a bit like 357 mag it makes some bigger gains in a 16 inch barrel than 45acp will
so then you have a short handy lever gun that can hold 10 rounds in the tube
are those gains enough to matter maybe not but the shoot ability of a short carbine increases your hit ration significantly at distance
now one ammo for your side arm and carbine.
it's a point many be not the greatest point

I'm going to adopt that saying. Glock17L and Glock G40

hypothetically you can rip off 16 rounds before you are empty from your Glock 40mos and you have to stop and reload your revolver at 6
so 16 or 6 rounds same time 2.67 times more rounds in basically the same weight package no reloads
reload time also much faster so in the time you can fire 7 rounds with the revolver the auto is 31 rounds in

yes you should train to not JAM the gun into anything when firing

If a bears on top of you dont wanna be fighting back hypothetically. Curl up on your belly and play dead. Few years ago a guide was attacked, he threw his glock 10mm to his client yelling to shoot the bear. Client couldnt figure out it had no manual safety and ended up running away. Guide was killed. Moral of the story, revolver or autoloader aint gonna help if you dont shoot.

Yikes! That reminds me of the saying "you don't have to outrun the bear you just have to outrun the slowest person you're with". It's hard to imagine running away with the gun while the guide gets chewed up.

I'll edit my reply.

hard to imagine trusting a client to shoot anything after being a guide for a while.

makes you think he was in some way incapacitated already or hadn't been a guide very long. although you would think if you can toss your gun you can fire it , hard to say we weren't there
and we have no idea how much of the story the client was actually telling

maybe more likely that the gun was knocked loose from the guides hand when hit and not really tossed , the guide then maybe pleaded for him to shoot it , shoot it and the guy froze then ran but had to explain why he had the gun after the fact so that is what he went with.

who knows we weren't there sounds like no one was.

real shame

Before I shot my first bear everyone in camp kept saying how nervous everyone was when they saw a bear and how hard it is to control your emotions. When I shot my first bear I didn't feel much different than when I shot a Raccoon, I mean heck I was in a tree stand, not like I was spearing it on the ground.

you also hang out of trees with a chain saw

have hundreds of coons killed

that is probably a lot different experience than others have.

people like to overthink things , when all they need is good muscle memory of bringing a gun to bear on a moving target , sounds like yours might have well been a deer from the tree stand and it hadn't a clue you were even there to shoot it till the shot was fired.

we had a portable electric remote clay thrower and had it set up that it would basically drop that clay about 10 feet to your left and 20 feet behind you , the thrower was protected by a plywood shield and out about 50 yards , the remote we could send them at you fast , dust one and the next one was on the way made you track and hit , if you got it a little close parts of the clay would shower down on you.
running this with a 18-20 inch barrel shotgun like you might be carrying for slug hunting or defense and you get familiar with it , and the limit wasn't 5 birds and you shot till you stopped it or it was past you and it was you need to keep topping off any time you get a break
learn to load while watching for incoming , be quick to shoulder , it isn't perfect training nothing is but it gets you quick.

pistol targets on a sled pulled at you can also build memory, the fist time you see a swinger or a peek-a-boo target that is activated by another target it seems so fast after a while you are trying to figure out if you can shoot the activator grab another target on the way and still get the activated target.

none of it is perfect but it all builds muscle memory and is a lot better than what most people do , a stationary target that is always in the same spot.

walking while shooting the pistol and engaging multiple targets learning to fire 2 rounds every time your foot hits the ground then transitioning to the next target during the stride

nothing is perfect but it all helps.

Black bear im assuming? They are kittens.

Yes Black bear. Grizzly hunts exceed my budget sadly.

The sheltered clay thrower tossing targets at you sounds like a blast! I gotta look into that, that would be a major hit with my friend group.
