Hey guys,
Working up a load for a re barreled 700 in 6 br. I am getting ejector marks, way sooner than I should. 6br no turn, 70 gr ballistic tips, 10x powder. Started at 28.7, quick loads shows 52k psi. Got ejector marks. Velocity is close to what quick loads shows. I dont usuall get ejector marks in my dasher till I get close to 70k. Theres no way I'm pushing 70k with that load. Primers look ok for a stock firing pin hole. Bolt handle has some resistance but not what I would call stiff. I ran it up to 30.2 gr.s which show have been the max. The bolt told me it was getting hot at that load. But it should have. Case head expansion was .0002'' max on the hottest load. That is compared to a new case, as this was the first firing. Anyone have this before?
