For your Black Powder Cartridge loads. Using wads made from the materials of vegetable fiber or low density polyethylene, I have recovered bullets from the snow and found the base of the bullets to be perfectly protected. Unlike many other materials I have tried, these are consistent top performers. These materials have been used to win at least many World Championship, National Championships, State Championships and set numerous National records along the way. Once a well kept secret, now available only here. NO OTHER MATERIAL COMES CLOSE!
