Winchester Drylok 12ga 3" - 25rd 10bx/cs 12ga 1 1/4oz #4

The Winchester Drylok 12ga 3" ammunition delivers reliable, weather-resistant performance for law enforcement, military, and tactical training applications. Purpose-built for harsh field conditions, these 25-round boxes feature Winchester's proven Drylok primer and powder seal technology, which resists moisture ingress and maintains consistent ignition even in wet, humid, or salt-air environments. Each round pairs dependable ballistics with weather protection—a critical combination for duty weapons, patrol rifles, and field operations where environmental exposure is unavoidable.

Each cartridge loads 1 1/4 ounces of #4 buckshot, a mid-range pellet size that balances pattern density and knockdown power across typical tactical engagement distances. The 3-inch magnum hull accommodates the heavier payload while maintaining reliable feeding and ejection in modern shotgun platforms. Drylok technology seals the primer pocket and powder charge against moisture, preventing corrosion and premature degradation—particularly valuable in coastal, jungle, or high-humidity deployments where conventional ammunition may degrade rapidly. The consistent powder seal ensures shot-to-shot velocity stability, supporting predictable point-of-impact and group integrity at combat distances.

Tactical operators, correctional agencies, and military units benefit most from Winchester Drylok's environmental durability during extended storage or field carry in challenging climates. The #4 buckshot load performs effectively from standard 18.5-inch tactical shotgun barrels and is compatible with all 12-gauge 3-inch shotgun platforms, including Remington 870, Mossberg 500/590, and semi-automatic systems. Law enforcement armories favor these rounds for ready-rack duty weapons exposed to weather, salt spray, or high-humidity storage. Available in 10-box cases, each containing 25 rounds, this ammunition suits both training cycles and operational readiness programs.
