Perhaps this is the place to ask this question. I never had a chance to either buy or sell bullets privately. Is selling bullets to a person and shipping it via USPS in violation of any federal laws? I am asking because I have erroneously purchased the wrong bullet type from Cabelas and when I called to ask how can I return it, they said due to federal regulations I cannot ship it back to them and would have to eventually take it to one of their stores for an exchange (not even a refund). Was intrigued by that reply.
