I am in the process of working of a load for my new barrel. 18" 1-8 twist intermediate gas sytem. I am loading the hornandy 68gr match HPBT in LC brass with CCI No. 31 brass. When I measure the headspace of the barrel how far should I bump back the shoulder? It is a match chamber so spec is slightly tighter than your standard mil-spec sammi chambers
