Old worn out cloth money bag from bank. Merely went into a bank and asked for an old worn out money bag, empty of course. They have plenty of them. Cloth is a little bit thicker than usually used for round ball patches. Soak it good with lube and it will slide into the barrel. Tight fit, good seal around ball for firing and cleans bore from previous fired ball. Don`t try seating the patched ball too hard or too fast. Go slow, or you could break your ramrod. Be sure patch is soaked well with lube and use a compressed fiberglass wood ramrod. These rods are usually longer than those that come with the rifle. Won`t interfere with shooting when repositioned under the barrel.
