Hi Guys,I need to reform some 30-06 brass into 8x57 to tighten up a mile of neck/chamber clearance.I never did this before.Do the cases grow or shrink when you fire form them?I guess I dont want a large gap from the case mouth to barrel for lead to flow into.If they grow upon firing and bottom out lengthwise i suppose thats bad too.Help.
