Iíve got my 270 for any rifle hunting of big game I wanna do, bow hunt mostly, but for bear calling in the timber Iím thinking a lever action 30-30 would be good. Any suggestions on a decent bullet for 100 yard and closer black bear? Iíve only taken whitetail with my 30-30 and that was a random box of core locks my dad handed me from the closet as a kid.
