WINCHESTER Super Speed 20/70 28g

Higher speed and controlled gas pressureThe secret of the new G2 powder lies in its controlled momentum, which results in a lower gas pressure for both combustion. The new Super Speed® Generation 2 36g is loaded with a higher quantity of powder, which increases its speed by almost 20 m/s while keeping the gas pressure below the 740 bar limit.Uniformity of the sheavesThe new Super Speed® Generation 2 is loaded with a Z-type plug with 4 compression ridges. Despite significantly higher velocities, this plastic cup plug with a specific design makes it possible to maintain the excellent regularity of the sheaves of the Super Speed® even at very long distances.Sealed star breech: The cartridge is completely sealed and the shot inside is perfectly protected, while at the same time increasing the regularity of the pressure release.
