Magnum Blend stacks three shot sizes in one hull: #5, #6, and #7 pellets made from HEVI-Shot's heavier than lead tungsten alloy. The mix patterns in layers, big pellets anchoring the load while the smaller sizes fill the pattern with extra strikes on a gobbler's head and neck.This 3 inch 20 gauge version carries a 1-1/4 ounce payload, serious weight for the smaller bore, and it turns a light walking gun into a legitimate turkey rig. A 5rd box is typical for premium tungsten turkey ammo, and a single box usually covers patterning work plus a full season in the woods.
