The Extra Bismuth cartridge, available in 12 or 20 gauge, is more than just a lead substitute. It allows you to approach the day's hunting with unprecedented confidence. Available with 4, 6 or 8 pellets, it is highly effective thanks to the properties of bismuth. The felt wad accompanies the 32-gram charge in all barrels, whether or not they have been tested with steel pellets. This environmentally-friendly ammunition contains no plastic, which will preserve your hunting area.
