sentences:  The cartridge became popular after World War II due to its high performance and flat trajectory, when German hunters were allowed again to own and hunt with full bore rifles.The 6.5×68mm's performance also made it that hunters who had problems with handling magnum cartridge recoil stepped down to less powerful but adequate medium cartridges like the 6.5×57mm Mauser, 7.92×57mm Mauser, 7×64mm (Brenneke) or .30-06 Springfield (also known as the 7.62×63mm in metric countries).Recoil sensitive shooters can fit an efficient muzzle brake to significantly reduce the amount of recoil.
