i only use 13o grain for my 270 in winchester super X power point or silver tips. 150 grain 270win by the winchester company are recommended for elk. In my opinion I want the bullet to travel to the game the quickest it can, so the 130grain is what I use. By the way my win. model 70 syn, featherweight prefer super x to remington core lock and all of the surpreme line of winchest, I have also used some less expessive 130grains from dunham's
