I'll forever be a fan of the 06. I can load her with 220gr accubonds and go to work. I do believe bigger bullets are the key. Just remeber to match up your ammo with type of game you are hunting. We all know that black bear is big game, so get a big game gun and bullet. If .270 is all you hunt with and your going on a bear hunt. get the heaviest bullet and practice practice practice so you can make yourself efficient enough to put the bullet where it count.
I have never black bear hunted but would like to. Does anybody wanna take an ole country boy from arkansas.
