My new 300PRC from Owens Armory should be done in the next two months...so when you guys get a new rifle, when do you begin load workup? Especially considering velocity increases during first 70-120 rounds of a new barrel....would load testing (ladder test, OCW, seating depth) be of any value during these first 100 rounds or so?
Or do you usually just shoot 100 rounds of factory ammo and then start working up custom loads???
