B&p Ammunition 12B78F29 Mach 12Gauge 2.75 7/8oz 9Shot 25 Per Box/10 Case, Shotshell Lead Loads

The Mach is the premier line of superior-performing shotshells. 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.
