Winchester Drylok 12ga 1300fp - 25rd 10bx/cs 3" 1-3/8oz #3 <

The Winchester Drylok 12ga 1300fp ammunition delivers reliable, weather-resistant performance for tactical operations, law enforcement training, and field hunting where moisture exposure is a concern. Specifically engineered for the Winchester Model 1300 pump shotgun platform and compatible with other 12-gauge receivers, this load combines Winchester's proven Drylok technology with dependable ballistics. Each 25-round box fits seamlessly into standard ammunition storage and field carry systems, making it a practical choice for operators who demand consistent performance in challenging environmental conditions.

Drylok ammunition incorporates Winchester's proprietary moisture-resistant primer sealing and case treatment, which significantly reduces corrosion and primer fouling in damp or humid climates—a critical factor in coastal operations, swamp environments, and extended storage scenarios. The 3-inch magnum shell loads 1-3/8 ounces of #3 shot, providing a balanced payload for medium-range patterns suitable for tactical applications, pest control, and hunting medium game. The #3 shot size delivers tighter clustering than larger pellet loads while maintaining sufficient energy retention at distance, and the 1-3/8-ounce charge ensures manageable recoil in rapid-fire training sequences without sacrificing knockdown effectiveness.

Law enforcement agencies, military training facilities, and civilian operators conducting regular shotgun drills benefit most from bulk purchasing in the 10-box case format, which optimizes cost per round while maintaining strict ammunition specifications across extended practice sessions. The Drylok treatment proves invaluable for duty ammunition storage in vehicles, duty bags, and field caches where traditional primers can fail prematurely. Compatibility extends across standard 12-gauge shotguns with 3-inch chambers; users should verify firearm specifications before loading, as some older or specialized receivers may require chronograph validation for duty or competition use.
