Are any of you guys forming brass from mil 7.62 to fit the necks better?
I found that forming 7.62 brass into Creedmoor leaves the necks thick enough to turn down to match the Ruger's slightly oversized chamber. In mine, the chamber neck is .297-.298", brass formed from commercial Win 308 is .292" (loaded), before neck turning. I turned my 7.62 brass to .2955" for a little better fit.
Also, mil 7.62 brass is strong enough to form it in one pass through the Creedmoor sizing die, with no intermediate steps.
