Like some here, I have used a 270 as my primary hunting rifle (for almost 30 years). I have been fortunate to take moose, black bear, caribou, sheep, mtn goat, and lots of deer with 130 and 150 gr corelokts. I discovered corelokt ULTRAS last year and they accounted for 9 whitetails. This year I used 150gr NPs, and they worked just fine. I'll stick with the NPs for a few more yearsas I bought 10 boxes ofFed Prem NPs foran unbelievably low price on closeout from wally world.
