However, if I was more worried about two-legged less-furry critters with opposable thumbs that may be shooting back at me, I would carry a bullet that gives me a high carry capacity but is still good enough to penetrate deep enough, and with modern HP technology, is assured to expand to 0.65 (or even more in the case of the 145gr Federal HST).
That would be the 9mm.
Thus, for semis, in bear country 10mm, and in human country 9mm. Why? Because each capitalizes on its specific strengths against specific targets.
145 grain HST should have been 147 grain HST. Typing on a phone
I live in bear and mountain lion country and moved up from a 9mm to 10mm (G20). I didn’t feel under gunned with a 9mm in town but honestly 15 rounds with double the muzzle energy isn’t a bad thing.
