My wife Eileen has killed a bunch of big game animals with the .270--and I mean big game, not deer, such as elk, moose and bison. She has never used a bullet heavier than 150 grains, and the biggest animal she's killed (a cow bison that weighed 900-1000 pounds) was taken with a 130-grain Barnes TSX. It went the farthest of any BIG game she's shot with the .270, just about 40 yards. The bull moose she shot with the 150-grain Partition took about a step and a half before piling up. Would heavier bullets have killed them quicker?
Chetaf, the answer.
