Forgive my question if it's naive, but as my wife likes to remind me, I'm not exactly the "outdoorsy" type. I've got a friend who is into hunting, etc. He claims that a 10mm is a fine caliber handgun for wild boar or Bear hunting. Now, I know enough to know not to ever get downrange from a 10mm, but can it really effectively take down a large North American Brown Bear? And as an aside, what about a nasty old, sharp tusked boar? Regards.
