I have found that if I wait about 10 mins between shots that helps and I only try to load and shoot within 1 min since the heat not only affects the sabot but it has some effect on the powder as well. I also have to keep an eye on the air temperature since here in Phoenix it gets hot fast and I try to shoot very early in the morning and even then I usually start out around 80*F. I currently shoot a T/C Encore using Pyrodex pellets 3x50,Shockwave 250gr, and VariFlame with sm rifleprimers. I wet clean between each shotfollowed by 2 dry wipes. I'm currently getting < 1 1/4 in consistently at 100 yards and haven't goneout beyond there, but that will change this week. Good luck on getting it figured out.
