Winchester Super Pheasant Diamond Grade is a high-performance upland load designed for the most demanding pheasant hunting conditions. These 12 Gauge 3 shells carry a heavy 1 5/8 oz payload of copper-plated lead 5 shot at a muzzle velocity of 1350 ft/s. The Diamond Grade series features Winchesters highest-quality lead shot, which is copper-plated to reduce pellet deformation and ensure tighter, more consistent patterns at extended ranges. This combination of heavy payload and high velocity provides the hard-hitting terminal energy necessary to ethically take down tough, late-season birds. 25 rounds per box. Recommended use: upland hunting. Safety Note Always verify your shotgun is specifically chambered for 12 Gauge 3 shells before use; do not attempt to use these in 2.75 chambers. Because this load contains lead shot, it is not for use in areas or for species (such as waterfowl) where non-toxic shot is legally required. Follow all standard firearm safety protocols and wear appropriate ear and eye protection.
