I have purchased some once fired IMI Match 308 brass. I have a small base die that I have used to resized most of it to SAAMI minimum chamber specifications. Unfortunately about 20% of the brass has sized too small it is approximately .003 to .008 thousands under SAAMI minimum. My question is this. Is this safe to shoot? If not is there a way to fireform it in a safe manner or should I just scrap it?
