Testing proves Wingmaster HD delivers the best combination of pellet energy and pattern density resulting in high energies delivered to the target.Features:12.0g/cc tungsten blendHigher retained energy - 6% denser than lead and 49% denser than steel with excellent patternsNearly as soft as steel - easier on barrels and choke tubes than other tungsten based productsExcellent choke response - choke response simulates leadRound, smooth true-sized pellets - dense, efficient patterns with deep penetrationDeeper penetration and more pellets on target
