Any avid waterfowl hunter knows they are going to get wet - its all part of the hunt - that's why Winchester designed Drylok Shotgun Shells. Using patented technology, Drylok cartridges keeps the shells dry and protected from the elements even in the worst possible conditions. The primer is lacquered to ensure the powder stays dry and the shot is steel plated for corrosion resistance. Other features include a two-piece double seal wad system ensures maximum water resistance and provides a greater gas seal for faster, consistent velocity. Additionally, a heavy wad design protects the barrels and provides tight patterns for long-range knock-down power.
