When I say the .280 RCBS Imp may be better than the .270, I'm using the criteria that its not significantly worse in any way, only marginally worse in some ways and marginally better in some ways. That is, it's not significantly worse in recoil, muzzle blast, or feeding from the magazine, same magazine capacity...but better in pushing the marginally bigger, heavier projectiles. The .270 will still be better for the marginally smaller game.
