Just did a few last night to test a new barrel on a Boys rifle that I did. RCBS Ammomaster press, RCBS dies (they came with the press) CH4D ram priming tool and a PACT powder scale. I only loaded 10rds for the test but I've done it before and wasn't testing ammo....I was testing the barrel. I worked great. There is a good amount of load data out there and components are available from various places. I've been using surplus military components with good result. 645 gr API bullets with 225gr of WC868 in Lake City cases with CCI BMG primers. Never ran this load over the chrono but probably will this summer.
