To be consistent with a muzzleloader you have to load consistently. Same routine everytime. I patch down and back one time with TC prelubed cleaning patches between shots to help make consistent pressure and it simulates a hunting bore after a fouling shot. Then I've had good luck with 300gr 44 cal jacketed pistol bullets with the MMP black high pressure sabot. I use two 777 pellets and a very slight film of bore butter on the sabot works very well for me. I group about 2" at 100 yards with a scope. I call that shooting error on my part as I'm just a fair shot
