The Platinum tips were great in my 500 S&W. Shot 3 deer with them, all 3 dropped in there tracks, and they were not spine shots. I tried the PT in my shotgun and I could get good consistant accuracy from box to box of ammunition. One box would shoot around a 1" group at 100yds. The next box would shoot 5" groups? I switched to the Federal 3" Barnes tipped expanders and have had good consistant groups again. But from what I saw with my 500 S&W this bullet is a great combination of expandtion on thin skinned game and penetration, if it shoots well in your gun this bullet is awesome.
