Ran some 7.62x39 brass through my Hornady 6mm ARC sizer die. The first two cases collapsed at the neck. Changed over to the 6.5 Grendel sizer & ran 10 more cases without any problem. Ran those 10 cases in the 6mm ARC die & they all sized down without any cases collapsing. So folks, it looks like 7.62x39 brass might need two sizing steps to get them to 6mm ARC.
I have no plans on reloading those cases. This was just an experiment. I have 100 rounds of 6mm ARC (Hornady 105gr BTHP) on the way from Graf & Sons. Tracking says Wednesday... :-)
