How much is a once fired box of Winchester 358win brass with original box etc. I have like close to around 350-500 rounds of once fired in factory box head-stamped brass i don't reload but but for some reason kept all the brass shot through my BLR and have been thinking of selling or trading to someone who could use it as soon i have an idea of what fair market value is i plan on putting it on the classified forum at a good price. justin
