Thank you~!The Sako 6mm PPC USA chamber has a neck dimensioned for brass which is of conventional thickness, not the "tight neck" found on many benchrest chambers. Sako brass has a neck of appropriate thickness for the Sako chamber. I'm not aware whether Norma 6mm PPC brass is made with a "pre-thinned" neck wall or if it is of conventional thickness. The head/body dimensions of either should be the same. Presumably, whether the Norma neck walls are thinner or not, the inside neck diameter should be the same as Sako brass once it is reduced by the sizing die then expanded to spec interior diameter by the expander ball.
If I had to guess at the powder and it is indeed VihtaVuori powder, I sure it would be VV133. That's what the benchrest crowd is using.Howdy,
Does anyone know what the OEM factory 6mm PPC USA 70 gr bthp sierras were loaded with? I pulled one, 22.5- 22.6 grains of short kernels extruded powder. VV120? VV130?
Thanks.
