I inherited a Remington 721 in 270 from my father. Dad always used 130 grain bullets for big game. The rifle is a nail driver. He was one of those people who were such a great shot it was weird. Always knew where the bullet was going. He used to hunt moose out of Vanderhoof B.C. and never felt he needed anything bigger for Moose although the guys he hunted with always kept a win 300mag in camp for any bears that tried to break in to the meat house before the bush planes could fly it out. The 270 is a great, flat shooting gun. For any of the deer speices, Pronghorn or black bear you can't go wrong.
