What are your guys thoughts on this caliber for a hunting caliber? I know its somewhere between the 308 and 30-06 in the power class. Im thinking about using it for whitetail which i know it will do the job. But also black bear the bear in the area i hunt run anywere from cub's up to maybe 450-600# being on the top end of the scale. I also applied for a PA elk tag will this caliber handle all of this? I will be using my hand loads 180gr Sierra game kings .311 dia. with a good charge of IMR 4350. and the rifle is a 43 IZZY 91/30 with a scout scope.
