I have been shooting muzzleloaders for a decade with the same ole 95gr of pyrodex and 240gr XTP. But this year finally found some good accuracy (around 2") with 3-777 pellets and 250gr barnes expander moving well over 2000fps. I hunted all day on Thursday with no horns and decided to get some table fare, and shot a doe at 40 yards with this load. All I can say is wow, it was devastating. Blew a 50 cent piece hole out the side of her. Blood was spatted on the trees, but she made it 50 yards down the hill. Inside it looked like she was shot with a 270win. Lungs was melted, heart blew to pieces, and extreme trauma to liver, and pancreas. I like it. Never seen some damage with my ole load for my old blackpowder loads.
