Were you able to find new 6 ARC brass? Where? How much? I have thinking about resizing 6.5 Grendel as my next step.
I have it on back order at Grafs, Precision Reloading, Midway, and MidSouth but no happiness for a whole year. I started by buying 200 rounds of loaded ammo in September 2021. My brass is still in good shape but has been loaded an average of 4X-5X.
