Im at 42.9 of varget (1.1gr below book max) on a suppressed PSA rifle length, rifle buffered LR308 firing hornady 178s. Its destroying the rims. Lantac enhanced bcg and superlative arms block opened all the way. I even threw in another tungsten weight in the buffer for a total of 6.4oz. Rough chamber maybe? I scoped it once and don't remember seeing anything out of the ordinary.
