I'm new to the world of Sabots. Until the Precession DC sabots I just couldn't get a sabot down the barrel after 2,3,4 shots. I've only about 20 of teh 300gr Dc's down the tube. Load great and no seeing any plastic fouling. Never cleaned every shot. Hell every muzzyloader I've own had a crap first shot then shots 2-7 just kept getting better. Wish I had an answer for ya. Good luck
