Home Forums Hunting & Shooting Ask The Gunwriters New Army cartridge announced to replace the 5.56 in service rifles and SAWs

Also Saami specs for 6.8 SPC is 55,000 psi. A 20% increase would be 66,000 psi. This is above the highest sammi max of 65,000 psi.

This is based on brass cased ammo. The rules may be different for the new polymer case stuff the military is looking at. But for the life of me,I don't see any polymer being tougher than brass.

I did read that ATK has developed a high velocity load for the 6.8SPC that uses a 90 grain Gold Dot bullet which is a bonded core bullet developed specifically for the cartridge that is being adopted by various military units around the world.
