So how about you answer to your flawed report. You yourself stated that one needs to stay off bone and to load it down because it is a lead conical and like all pure lead conicals it will expand to fast at higher speeds or on contact with heavy bone. Those were your words not mine. Now, just what is an adult black bears shoulder made of? Pretty damn heavy bone. Even the scapula on an adult male is pretty thick. Your experience with black bear must be with the little 160-200 pound little fellows. Mine is with the 400-500+ pound ones that can take your head off with a single swipe.
This argument got started by advising someone with little black bear hunting experience to use a proven poor penetrating bullet from a single shot muzzleloader. That borders on a serious safety issue in my book. I've had the audacity and pure stupidity to hunt them with round ball but even my round ball mixes come in to 8.5-9 BHN and they punch pretty well through bone. I certainly wouldn't recommend and inexperienced bear hunter to use them any more than I would recommend anyone to use any poor performing bullet. That is the main point. And any bullet that even the advertisers say you need to load down and stay off heavy bone is not a bullet I would recommend. It's just that simple.
