I have 250+ pcs of R-P 7.62x39, 168 Pcs of Win 7.62x39 and 100 pcs of NEW IMI 7.62x39 brass
I'm looking for 6.5 Grendel (and any 9.3x64 that you might have).
Yes I know I can neck it down and fireform it. That has worked with the Win but not the R-P. Seems the R-P is softer and the shoulder buckles. Less annealing if you are leaving it as 7.62x39!!
