[QUOTE="entoptics, post: 1833136, member: 104268"] I've been a budget minded reloader from the start, and it occurred to me, that perhaps once fire brass is [U][I]better[/I][/U] than brand new brass when starting a new rifle (factory or build). 1) I've measured a lot of factory new brass, and it's always been well below SAAMI minimum in base to shoulder and sometimes even OAL. 2) I've measured a lot of fired brass, and the worst chamber I've seen leaves them just a hair over SAAMI max. Taking observations 1 and 2 into account, I've found that sizing a random once fired piece of brass back to the specification of any chamber I've measured, is less reforming movement than would have occurred if I'd fire formed new brass. In other words, every single piece of once fired brass that I've repurposed for another chamber, was closer to that chamber, than a new piece of brass would have been. My theory is that a 60,000 psi fire forming process in a SAAMI chamber will get you a lot closer to "ideal for my particular rifle" than the bash/smash/stretch process required for creating a new piece of brass on a factory assembly line (no matter how high end). It also might "hammer out" other variations, making it easier to assess uniformity. What do you all think? [/QUOTE]
