I shot a few moose over the years with a 375H&H loaded with 300gr Partitions @ 2475fps recovered most of the bullets.
Had a butcher ask me why we shoot one of these moose with a 22LR = he had found what he thought was a 22LR lead bullet while he was cutting the moose up.
He didn't realize that it was the front portion of the Partition that had seperated from the jacket until I slipped the two pieces together for him.
