An intermediate cartridge is a rifle/carbine cartridge that has significantly greater power than a pistol cartridge but still has a reduced muzzle energy compared to fully powered cartridges (such as the .303 British, 7.62×54mmR, 7.65×53mm Mauser, 7.92×57mm Mauser, 7.7×58mm Arisaka, .30-06 Springfield, or 7.62×51mm NATO), and therefore is ...
The 6.5 Grendel bullets have a true diameter of 6.71mm / 0.264" and the 6.5 Grendel case can be formed from abundant 7.62x39 cases with a neck re-sizing die, and fire-forming a slight change to the shoulder, if the case is made from brass. Many of the popular 7.62x39 cases are made from steel, which will not work for reforming the shoulder.
The 7.62mm CETME had a lighter full-metal-jacketed, plastic-cored lead bullet with a reduced powder charge.
