bears can't read ballastics charts nor can they understand energy or velocity, i finally figured this out after around my 80th brown/grizzly bear....
they do however understand holes in their vitals. best kills for clients has been with .30-'06's or 300 winmag. larger calibers have been less than impressive, but still kill them just fine. i'd be less worried about which kinda bullet your choosing as where you stick the bullet you choose. this is one of those, don't over think it deals.
everything you said will work and when its all over with you'll never know if a different one woulda worked any better or worse. shoot straight, shoot often. have fun.
