There's some fired Norma 6PPC brass for sale on Gunbroker, and the seller has turned the necks to .009", indicating that this gives a loaded round dimension of .261". He then states this brass will fit the Sako factory rifles and others so chambered, and is not for BR work. I was under the impression that Sako chambered the 6PPC with a neck dimension of .272", and would think this brass too thin. Anybody know for sure what Sako 6PPC chamber specs are? Thanks!
