B&P Mach Features The B&P Mach shotshell is built around the innovative Gordon Case a wad system that reduces developed pressure while limiting recoil effects producing a noticeably softer-shooting shell without sacrificing pattern performance. The conical shape of the Gordon base wad optimizes powder combustion translating F2 powder s energy into a more consistent muzzle velocity of 1300 fps. This attention to internal ballistics is why the Mach line carries a competition history that includes multiple Olympic Gold Medals and World Cup Finals wins. The base wad s four concentric rings help stabilize the shot column as it travels down the 12 Gauge bore. Loaded with #8 lead shot at 1 ounce the Mach is tuned for trap and skeet disciplines where dense even patterns at moderate range are essential for breaking targets consistently. The low brass hull and 209 primer combination keeps the shell reliable across a range of semi-auto and break-action shotguns. Each box holds 25 rounds giving shooters enough shells to work through a full round of clays without frequent reloading of the belt or vest. Serious clays shooters looking for shells built on the same technology trusted at the highest levels of competition will find the Mach a dependable choice.
