Forty or more years ago, you weren't worth damn in Wyoming if you did't shoot a 270 for Elk. We shot a boat load with 150 Core Lock's off the self in a factory Remington box. Once I started hand loading we tried the Nosler Partitions and after several Elk we all decided there wasn't much difference and went back to the old Remingtons. I haven't shot them in a long while, but something never change.
