 This was accomplished by fitting an efficient muzzle brake to significantly reduce the amount of recoil for recoil sensitive shooters.With the help of a muzzle brake the 8×68mm S recoil is reduced to tolerable levels.Extremely thick brass results in 'only' 5.58 ml (86 grains) H2O cartridge case capacity for the 8×68mm S. A rare feature of this German rimless bottlenecked centerfire cartridge design is that it has a slightly rebated rim (P1 - R1 = 0.3 mm).
