The Mach is a premier line of superior performing shotshells will satisfy even the most demanding Trap and Skeet shooters. These high-end, premium shells utilize the innovative Gordon Case for superior performance. The Gordon case wad allows a reduction in the pressure developed but mainly limits the effects of recoil, making the shot softer while providing excellent performance. The conical shape of the Gordon base wad optimizes the combustion of the powder and, consequently, the performance of the ammunition. The base is slightly larger in diameter than the body of the cylinder and is formed by four concentric rings.
