I started working on a 130 gr load for my Mk V 270 .120 rounds later I was ready to concede it did not like 130 gr bullets. I loaded a few rounds of 150 gr Hornady spire points with a max dose of 7828. That load gave me a 3 shot nickel sized group repeatedly at 100 yards. I haven't shot another load thru it since. 24" barrel and my chronograph said an avg of 3153 fps. That load kills deer and antelope rfn. Can't even imagine going thru 6 different boxes of 60 -100 dollar ammo to figure out what it likes to shoot. Mb
