The Apex Stratified(TM) S3 Steel in 20 Gauge is a premium non-toxic waterfowl shotshell engineered around a genuinely innovative concept: a layered dual-size shot payload. Each 3" shell delivers 1 oz of zinc-coated S3 steel shot loaded with both #2 and #4 pellets in a stratified stack. When the shell fires both shot sizes pattern together - the #4 pellets deliver dense mid-range coverage while the larger #2 pellets carry the energy needed for deeper penetration at distance. The result is a single shell that performs across the full range of distances encountered during a real waterfowl hunt.Apex Stratified S3 Steel 20 Gauge 3" 1 Oz #2/#425 rounds per box; 10 boxes per case (250 rounds)Muzzle velocity: 1 300 fpsShot payload: 1 oz zinc-coated (plated) S3 steelLayered shot sizes: #2 and #4 in a single shellUltra-durable one-piece wad system derived from Apex's TSS platformNon-toxic / lead-free - legal for waterfowl hunting in all U.S. jurisdictionsAssembled in the USA by veteran-owned Apex AmmunitionEngineered for duck and goose hunters who face close decoy shots and long passing shots in the same outing the Stratified S3 Steel eliminates the guesswork of choosing between shot sizes.
