The older berdan primed stuff was more accurate in my match M1a than the 79 or 80's ammo. And the same in my other 308 bolts as well.
That said, it is decent ammo in all forms. I've reloaded the boxer brass with excellent success and results.
Water capacity I found its interior capacity to be close to a bunch of brass I had from a lot of winchester 168 grain match bulk purchase I had years ago and had similar results on paper.
