The full-loaded 270 is hard on lightly constructed bullets
So Dave...You don't like the Berger either? I have had nothing but good luck with 130 Sierra's on Deer out of the 270 Win even an Elk or two, but like your comment,it changed me to a stouter bullet for both Deer and Elk in the 270 on the same hunt.
But that was a long time ago when I turned Nosler when Nosler wasn't kool....The Sierra's of old may have been better/tougher than the new breed..I have no clue.
