ASC mags are too short. A round loaded to 2.310 doesn't come close. It appears the max is around 2.270. Disappointing because I happen to have a ASC 6.5 grendel mag and a round loaded to 2.310 goes in just fine. I did modify the PRI mag so it goes into the lower, but it's not ideal. I can still try an elander and HK maritime mag.

The BTM is a low-speed mill that primarily grinds coal by impact and attrition. The VRM is a medium- speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed
