So in response to this thread I did an audit of my .223/5.56. lets just say I have a lot. I find this ammo can marked with an old and crumbling piece of medical tape. Written in pen is "Unprocessed commercial .223 brass" my writing. Inside is 51 boxes of Winchester 62 grain White Box, same lot...Score! Kinda like finding an unknown 20 dollar bill in the jeans...![]()
