Winchester Bismuth 20 gauge shotgun ammunition delivers a premium, non-toxic shot option built for waterfowl hunters and clay shooters who need reliable, environmentally responsible performance. These 3-inch shells load 1 1/8 oz of tin-plated bismuth shot in #4 size, traveling downrange at 1300 fps—fast enough to reach birds at 60 yards while the rounded bismuth pellets pattern cleanly through any choke. If you hunt where lead shot is restricted or simply prefer a harder-hitting, non-toxic round, Winchester's bismuth load handles both duty and regulation without compromise.
The tin plating on each bismuth pellet isn't cosmetic—it protects the shot from deformation in the bore, meaning tighter patterns and more consistent hits. The buffered payload maximizes pellet count on target, an advantage when you're working distance or brush. Winchester's water-resistant lacquered primer and double seal keep moisture out of the case, so these rounds stay reliable whether you're pulling them from a blind on a wet morning or running them through your truck for a week of upland season.
You get 25 rounds per box—a practical field count that works for both practice and serious hunting. Bismuth cycles smoothly in most modern 20-gauge shotguns, though pattern testing in your specific gun is always wise. For hunters in non-lead zones or shooters who've committed to bismuth, Winchester's formula represents solid, proven ammunition backed by a century of shotshell engineering.

Yes. Bismuth is a non-toxic shot material that meets federal and most state waterfowl regulations. Always verify your local hunting regulations, but these rounds are designed for birds and comply with non-lead requirements in most of North America.
Bismuth cycles in standard modern 20-gauge shotguns without special modifications. Because bismuth is harder than lead, it patterns tightly and reliably. If you own an older shotgun, consult the manufacturer—most contemporary 20-gauges handle bismuth without issue.
Bismuth is denser and harder than steel, which means it retains energy better downrange and patterns more consistently. It's also gentler on older gun barrels. Steel shot is cheaper but requires tighter patterns to be equally effective at distance.
Each box contains 25 rounds, a standard field count for a day of hunting or practice.
