6.8 Remington SPC (6.8×43)


6.8 Remington SPC (6.8×43)

The 6.8mm Remington is another attempt to produce an ‘ideal’ assault rifle cartridge which would provide good terminal effectiveness (stopping and killing power) from short, carbine barrels out to 300 meters, while having dimensions and recoil close to 5.56×45 NATO (which lacks terminal effectiveness, especially when fired from short carbines). This cartridge was commercially developed by Remington with collaboration from some members of US Special forces, and the 6.8mm ammunition and weapons were apparently tested by US Military, but none were adopted so far. The 6.8 Rem SPC is, to certain extent, a direct rival to the 6.5 Grendel round described above. Today, the 6.8 Rem ammunition is manufactured commercialy in USA, and few weapons are available to fire this round.
