Boretech Rimfire Blend 16oz
This bore cleaner is designed specifically for cleaning rimfire barrels. It aggressively attacks lead, powder, and other fouling. We use this product on our own newer rifles, and have also successfully cleaned up some very old Winchester 52's that were in very poor condition.
This product was designed specifically for removing lead fouling in rifles and handguns. Those shooting cast bullets might want to make this part of your cleaning arsenal. Works great for rifles as well as handguns.
