Winchester Bismuth delivers the non-toxic shotgun performance waterfowl hunters have been waiting for. These 3-inch shells pack 1-3/8 ounces of tin-plated bismuth shot with a muzzle velocity of 1450 fps, giving you the stopping power and pattern consistency that rival old lead loads.
What sets these apart is Winchester's buffering technology. The buffered payload cushions each pellet during ignition, preventing deformation and fracturing while keeping more pellets in a tight pattern. That translates to measurably denser patterns at 60 yards compared to standard bismuth loads, which matters when you're threading shots through decoys or taking birds at extended range.
The tin-plated bismuth pellets themselves are engineered for consistency. Winchester produces them smooth and round to maintain shape through the shot column and downrange. Bismuth is significantly denser than steel, roughly 23 percent denser, which means better energy retention and deeper penetration without the barrel wear issues that come with steel. It's also one of the softer non-toxic materials, making it safe for older shotguns and classic doubles that can't handle modern steel shot.
These shells are built for the realities of waterfowl hunting. Water-resistant lacquered primers and a double seal wad system keep moisture out of the powder pocket and primer, so shells you accidentally soak in the marsh or leave in wet conditions will still fire reliably. The two-piece wad design ensures a tight gas seal for consistent velocity round after round.
#1 shot is the go-to choice for geese and larger ducks. It provides the pellet count you need while delivering knockdown authority on bigger birds.
Yes, bismuth is safe for classic and older shotguns because it's softer than steel and won't damage barrels or cause excess wear. Always verify your shotgun's manual first, especially with valuable vintage firearms, but bismuth is generally one of the gentler non-toxic options for fixed choke and double barrel shotguns.
The buffering material fills voids between pellets and cushions them during ignition, preventing deformation and fracturing. This keeps pellets rounder and more consistent, resulting in denser patterns. Winchester reports 50% more pellets in a 30-inch circle at 60 yards compared to non-buffered bismuth loads.
Bismuth is roughly 23 percent denser than steel, delivering better energy retention and deeper penetration downrange. It also patterns tighter through most chokes and maintains velocity better at distance. The tradeoff is cost, as bismuth loads run higher per round than steel alternatives.
Yes. Winchester includes water-resistant lacquered primers and a double seal wad system specifically designed to keep moisture away from the powder pocket and primer. These are built to handle marsh hunting and accidental dunking.
