Actually any premium 7mm bullet of 140 gr and up work fine on moose and elk.I have killed several moose and elk with the 140gr partition out of both the 7mmrem mag and 7mmstw.Even with a muzzle velocity of 3500fps the 140 gr partitions held together fine and penetrated just as well as heavier partitions.The140gr and up failsafe and barnes x are also fine choices.
