The issue is that as I continue to shoot more than 5 shots, even after removing the plug and giving it a thorough field cleaning, the accuracy starts to seriously deteriorate.
This happens with most powders. Pyrodex is one of the best powders out there but it is dirty. 150 grains of Pyrodex pellets leave a lot of fouling in the bore. When firing Pyrodex i swab the bore with a patch wetted with Windex with vinegar after every shot. Then i follow up with two dry patches. i never remove the breech plug at the range unless there is a misfire or something.

JSG and Pinnacle are clean burning powders. Awhile back i fired ten rounds without swabbing the bore using 100 grains of Pinnacle and the 250 grain SST. Distance was 100 meters and all ten bullets went into a <2.5" inch group.
