[QUOTE="25WSM, post: 1769472, member: 38048"] I never give it much thought when doing a new barrel I assess how many brass I need for the life of the barrel. Typically 100 to 200 pieces. By the time your done the barrel 1)will be broken in or very close to 2)have perfect brass. 3(know if there are certain bullets it hates. Then you'd be ready to get it done. Plus fire form loads can be tuned to shoot crazy good. I had a 243AI and 6BRA that routinely shot 1/4 moa so that gives you a good local match load or an accurate game load. I saw someone say they skip lube on body when fire forming. Don't. Even a shell with a .001 setback will get .006 to .010 of the shoulder driven back when the firing pin strikes. You definatly want that base to slide back on the bolt face before it fills in the new areas. Any body can test this by just meaduring before and after with a live primer. Who would think a firing pin fall would crush the brass any at all. Shep [/QUOTE]
