damn, either one would do it... a light reload was what i was wondering about, if the case isn't full and there's empty space along the top of the powder when the round loads it can flash over and cause heap big overpressure too
Speculation over on AR15.COM centers on the ammo. Witnesses to similar live-fire exercises have said that the projectile is a modified 3” naval AP round as there aren’t any 76mm projectiles. They turn the round on a lathe until they achieve the proper diameter for the main gun. If not done correctly you’re looking at an over pressure to the gun that could cause a breach failure.
There was also talk of reloading problems with un-sized brass catridges.
