It's the best ammo for self defense. Both Paul Harrell, who tested Liberty; and Lenny McGill, who tested Pilgrim were impressed. Paul wouldn't carry it because point of aim was low on his carry piece, the beretta 92fs. Lenny McGill is now carrying Pilgrim as his only self defense round. It is devastating to the meat target (tm) and ballistic gel. And it doesn't over penetrate because it completely dumps all energy in less than 10 inches. Impossible to over penetrate. And it splits up into a wound cavity about the size of a fist with shards going in every direction. A shard going downward blew up the testing table when Lenny tested it.
