I have some 5.56/.223 brass I want to sell, but I’m wondering if I need to clean it before shipping. Will USPS or UPS have a problem? I have no idea what they’re doing for security these days, and I’m just thinking a scanner or search dog might alert on it due to powder residue.
I would say no they don’t have to be cleaned prior to shipping. I just bought a Hornady L-n-L from a fellow forum member & he threw in +/- 500 free once fired .223 brass. They still have spent primers & powder residue all over them & they weren’t any questions asked.
