What powder are you using? What caps or primers are you using? I have an Accura as well and noticed a definite "crud" ring that forms with Triple 7 and musket caps. Not that bad after only 1 shot, but if you don't get the crud ring out it can build up over many shots and I could see it causing loading issues. I shoot Hornady 250 gr SSTs in my Accura and don't have loading issues until about shot 4 or 5 without running a patch down between shots.
