At 40 yards, Winchester Bismuth puts an impressive 90% of the pattern on the target while the two closest competitors demonstrate 66% and 54%. Hunters can also use any choke with Winchester Bismuth for optimum pattern performance. Another important component of Winchester Bismuth is the Winchester Drylok Wad System and primer system for those days that are not bluebird but when the birds are flying all the same. The proprietary Drylok Wad System keeps powder dry for consistent and dependable ignition despite damp waterfowl conditions.Bismuth shot has gained popularity among die-hard waterfowlers because it is denser than steel, allowing for smaller shot sizes to be used and more pellets within a pattern. It is also less likely to damage older shotguns and performs better than steel through a variety of chokes.The 3-inch 12-gauge items will be loaded with 1 3/8 ounces of No. 4 shot for ducks and No. 1 shot for decoying geese with a muzzle velocity of 1,450 fps. Bismuth 20-gauge is available in a 3-inch with 1 1/8 ounces of No. 4 shot, traveling at 1,300 fps. Winchester Bismuth will be available in 2022 in 25-cartridge boxes at a price meant for dropping birds, not breaking the bank.
