They worked fine for deer sized aniamals but failed to penetrate an elk's rib cage, not once, not twice but three shots blew up on the ribs. Killed the bull with a head shot after I figured out what was going on. Switched to the Remington 120 grain and am delighted with it. Have some Partition Noslers that have been sitting around for year, don't need to switch any more.
Good shooting!
