Quickly Removes Accuracy-Robbing Bore Fouling
Non-abrasive solvent easily cleans out lead, copper, wax, and even shotgun wad plastic. Quickly strips carbon buildup in the throat area, and regular application of a few patches soaked with Butch’s during a match or shooting session will control copper fouling. Safe to use on all barrel steels; may be left in barrel overnight without harm.
