Has anyone else experienced plastic fouling in their muzzleloaders from using bullets with plastic sabots. I have a CVA Firebolt and after shooting about 50 rounds through it I noticed some fouling that I couldn't get out. It finally dawned on me that it was from the sabots on the Powerbelt bullets. I put a cork in one end of the barrel and filled it with Ed's Red bore cleaner and let it sit for a few days. The acetone in the mix loosened the crud up enough that a brass Bristle brush pushed through took the fouling out of the bore. My bore looks like new again.
