A Buddy of mine showed me a 308 He had bought. Older gentleman threw in 200 rds ammo, some factory and some He had reloaded. About 1/2 reloads were headstamped 30-06. We shot a few and they shot ok. Would you just trim the necks waay back, run through a 308 die then trim to length? Seems like a lota trouble especially when 308 brass is cheaper and easier to come by
