The .357Mag and the 10mm are very similar in terms of energy and momentum.Don't get a 10mm because you don't think the .357 Mag isn't enough for black bear. It is, if YOU are. And, if YOU aren't, a 10mm won't change that.
And in the end, bear spray really is the answer for bear protection.

I'm a weekend hiker in Utah. I shoot well and have no problem picking up most guns and shooting well.
I carry bear spray and don't find my bear defense info from gun forums.
Now that behind, it's clear the OP just wants a 10mm. Go for it. The truly helpful thing I'll say, 40 is usually measured with a compact handgun barrel and 10mm typically is measure not with a compact barrel. If barrel length matters (and it really seems to matter to 10mm shooters), I would find comparisons of 40 in the same barrel length and *I* would hunt for the actual bullet I would want (XTP for bear if I wanted JHP) vs the speed of a bullet not designed to before with massive speed or a bullet that needs massive speed to perform at all.
And then I would look really hard at what all copper rounds do if I wanted to shoot "outdoor" labeled FMJ. Hard cast isn't magic. It has copper in it to harden it. An all copper round is going to be harder than any blend of softer metals found in "hard cast." Weight also doesn't seem to matter in all copper rounds as they just zip through time and space compared to FMJ.
Fmj and the lehigh extreme penetrators act a little different. While I agree they penetrate similarly, the scalloped design of the lehighs tends to take tissue into the slots and eject it out the side creating a much better wound channel than a round nose fmj. A good friend of mine loves his wide flat nose lead bullets. And having put some through ballistics gel I can see why the flat nose does something to make the wound channel bigger, even then the lehighs we shot that day. And better than round nose fmj. I'm hoping to try some truncated cone flat points soon to see if they act similarly to the wide flats.I stand corrected on content of hard cast
The Kel Tec forum had a thread on hard cast shattering on bone, which I never heard got brought up by hard cast fans. In my world of understanding, metal becomes brittle when it
I guess it's my opinion that Legigh bullets, just purchased by Wilson Combat, is better for an outdoor load and that all FMJ do the same thing on target.
I have provided incorrect info, but the general cut of my jib is pretty much confirmed by others here too
I've tested a couple 44mag hardcast bullets on Elk knuckles. The first, a Lazercast 240gr "silver" bullet broke up and exited in pieces. The second, a 240gr "Keith",. 18bhn, by MBC exited intact. My observation is that it is entirely possible to make a cast lead bullet too hard.I stand corrected on content of hard cast

The vanilla hardcast exceeded 64" - the max of blocks he had setup.Your link follows all other testing. The all copper "cross" shaped Legigh bullets went extreme depths?
" 47 inches from 9mm"
No caliber in FMJ truncated or round nose is going 47" in gel.
It's not a gimmick to say they truly are "extreme" in penetration. Nothing bests that? and it comes from the same company you are going to have to buy from to get "nuclear" 10mm that will do less.

This is the standard .38 Special load, albeit under weight by 8 grains...for bear?....Something bigger, with more velocity and a heavier bullet, makes more sense.FPS almost is that last important thing. Look at the 800FPS Micro 150gr HST in 9mm. It's the hammer of Thor in jacketed hollow points.
A jacketed hollowpoint is the last thing to use on a grizz. You need as much penetration as possible to get through all the fat, muscle, and bone in those critters. Hence, heavy hardcast bullets. A .45-70 with an Aimpoint on top would be my choice.FPS almost is that last important thing. Look at the 800FPS Micro 150gr HST in 9mm. It's the hammer of Thor in jacketed hollow points.
