Manufactured of a tungsten-nickel-iron alloy, HEVI·SHOT is 10% denser (heavier) than lead and an amazing 54% denser than steel. This significant density increase is unmatched in any other shot material and translates into greater per-pellet energy at virtually all distances. Compared to steel shot, there simply is no comparison — in retained energy or pattern density. Shooting an equal payload and shot size, HEVI·SHOT pellets have 25% more energy at 50 yards than steel pellets have at 30 yards. This allows you to drop down three shot sizes to maintain pattern energy and dramatically increase on-game pellet count. The resulting HEVI·SHOT patterning, with full chokes, yields an average of 88% efficiency.
