I'm looking for recommendations for a good .270 factory load for elk. I had previously shot either a .30-06 or .300 WSM, but last year I scaled back to a .270 Kimber Mountain Ascent rifle. I love the rifle and it is great to carry, but I wasn't happy with my bullet performance last year. I was shooting 150 gr Winchester Super X Power Point loads, and I shot my bull at 250 yards. I put 2 shots into his chest, but when I walked up on him 15 minutes later he still got up and ran. I finished him off with a shot in the neck as he ran. When field dressing the bull, I noticed that at least one bullet was really fragmented, with poor weight retention. I was thinking about possibly trying Federal Premium loads with a 150 gr Nosler Partition. Does anyone have experience with these, or have another recommendation?
