Remington Wingmaster HD 12 Gauge 1 1/4oz 3in #4 Centerfire Shotgun Ammo 10 Rounds. Simply put Wingmaster HD achieves higher density and patterning than competing shot shells whose formula is relegated to second place. In fact testing proves that no other shotshell on the market can deliver the same combination of pellet energy and density as well as ultimately result in high pattern energy on target. We have upgraded the technology used to make the shotshell to deliver even more knockdown power. The Wingmaster HD line utilizes tungsten powder - a material 6percent denser than lead and 49percent denser than steel - for even more dense pellets and heavy metal impact energy.
