  • The 6.8mm Remington SPC (Special Purpose Cartridge) is a modern, short-action rifle cartridge that was developed by Remington Arms in collaboration with the U.S. Army for use in the M4 and M16A4 service rifles. The goal was to bridge the gap between 5.56mm NATO and 7.62mm NATO cartridges, and the 6.8mm Rem SPC does a great job of it.The 6.8mm Rem SPC has an effective range of up to 500 yards when used with match grade ammo and can take down medium-sized game such as deer, hogs, and black bear with ease at close to mid ranges when using proper bullets and loads. It also provides more stopping power than its 5.56mm counterpart, making it a great choice for home defense purposes as well as hunting.
