I shoot a fair amount of slugs and trap shoot twice a week (100 shells each day). I don't seem to have much problem keeping the barrel clean, but have read that generic wads (Claybuster, etc.) cause more plastic fouling than the name brands (to include Windjammer and others). Anyone else run into this? Also, what do you use to remove the plastic buildup (I use brake cleaner and a brush). Thanks for all the info.
