From the reading I have done the pressure is really high on the military rounds from sig. the cases in guns and ammo or shooting times had a steel bottom to handle the pressure.

I still don't understand the 6.8 mm (.277") over 6.5 mm (.264") for this application

Problem has always been the diameter of the bullet realative to the wound size. Thr 5.56 has plenty of power, but too small of a bullet. 30 cal and above is the right approach. Only exception would be the anemic. 30 carbine. Myself personally. I refer .30 cal, namely the .308. I used it the Army and i still used it in the civilian world. Don't fix whats not broken. Sarge
