Chad, I'd be happy to help.
The brass is treated exactly like 30BR brass...just neck up, trim, and neck turn 6.5 Grendel brass. Lapua makes the brass and it is of very good quality, has small primer and small flash holes. It yields a 30 caliber case with a ppc case head and a capacity right between a BR and a ppc. Very easy to make and get to shoot.
I can supply both dies for it. I use a Redding competition seater die, but as Greg said, a wilson type die is just as doable.
Give me a call if you want. It'd be good talking to you anyway. --Mike 270-542-6022
