Higher speed and controlled gas pressureThe secret of the new powder G2 lies in its controlled "momentum," which is reflected in a lower gas pressure during combustion. The new Super Speed® Generation 2 36g is loaded with a higher amount of powder, increasing its speed by almost 20 m/s while keeping the gas pressure below the 740 bar limit.Uniformity of the shotThe new Super Speed® Generation 2 is loaded with a "Z" type wad with 4 compression ribs. Despite significantly higher speeds, this specially designed plastic cup wad allows for the excellent uniformity of the Super Speed® shot even at very long distances.Sealed star crimp: The cartridge is completely sealed, and the shot inside is perfectly protected, while also increasing the uniformity of pressure release. Lead shot cartridges.
