I have a Knight Wolverine that with 80 gains of Triple Se7en and a 240 gr .45 caliber XTP it is a sweet shooter. Another person I know hunts with that sameload out of a Knight Bighorn, and shot a big Kansas whitetail and he said at 70 yards that little XTP blew right through. Said it left a blood trail anyone could follow. Good luck with your new powder. Watch for crude build up, and swab between shots. I think you will like loose powder.
