The C&R can be a great convenience, especially when traveling or at a distant show. For shipments, it is a little iffy; some will ship to a C&R and some won't. Bear in mind that it not only does not authorize selling, but can actually inhibit it. I would be reluctant to do a lot of selling and trading of guns I had bought on my C&R. It is not forbidden by any means, but you are theoretically open to inspection by the ATF, and as far as I know, engaging in "the Business" is at best poorly defined.
