I have been useing a Pre-64 M70 in 270 Win. for over 45 years shooting nothing but 130 gr. bullets. The only animal I ever had run after being hit was a Blackbuck. I did finally recover him. In 1972 I loaded up some 270s with Win. cases, 130 gr. Hornadys with 60 grs. of H4831 and went to Ontario for a Black Bear hunt. I was in a boat fishing off shore when I saw a very large bear on the shore edge feeding. We stopped the boat and I took the shot from about 85 yards. When the bullet hit, the bear jumped straight up in the air, did a flip and landed in the lake. When I got to him he was dead in the water. 130 gr. 270s will kill most anything if you hit them right.
