Does anybody know the pressure of a Mil-Spec HPT and or High Pressure Test round? Are people aware that while the Nato Standard pressure in 7.62x51 rounds are 50,000 to 55,000 psi, the weapons themselves are designed to handle significantly higher pressure up 67,500 psi. HPT Rounds fire @67,500 psi for a very specific reason, Due to the availability of 308 winchester ammo. D.o.D Specs require a soldier to be able to fire civillian ammo due to the fact that a soldier can scavange civillian ammo if need be.
This argument persists and no body ever makes the same claims about 5.56/.223 ammo. Why is that?
Do you honestly believe a Drill instructor would endanger a trainee by telling him he can scange 308 win ammo for his M60 machinegun? Why would the DI say that if it would kill or maime the Soldier. While hot bodies may or may not be expendable in wartime equipment isn't, the logistics of supplying a foot soldier and getting him an new M-60 and or SAW are next to impossible. Why would soldiers be Trained to risk damage to a weapon? (if you have served you know the military is almost if not more protective of equipment than Soldiers)
Everybody talks about the pressure of the rounds themselves and nobody talks about the max operating pressure of the Weapons. Why is that?
I am certain if they did it would destroy the credibility of an argument that says you should never fire Civillian .308 in a 7.62x51 mm weapon.
