Luke, I forgot to ask before. Are you using a sabot solvent after every 4-6 shots? Even with Powerbelts, after a few shots it gets damn hard to drive in a bullet because of plastic residue. I use CVA Sabot Solvent but the stuff is nasty and it will do damage to a plastic stock. I don't worry about that because I remove my barrel when I clean my gun. I hear that Hoppes Benchrest works well also to remove plastic residue. Brownells makes one but the reviews are not as good.
