I used the FederalPremium Vital-Shok and went by "the .270 was made for a 130 grain bullet" theory" and did well. My complaint was the bullets always passed through and the animal ran a good ways before going down.

I switched to the Winchester 140 gr. Supreme Fail Safe and most of the time I only had an entrance wound, and the animal either dropped or walked a few steps and fell dead.

Any of the quality hunting ammo is good. When I find something that works I will go buy as much as I can afford and find of the same lot number. Thus the later will be in my hunting rifles for several more years. MV out!
