As I understand it I can ship a rifle out-of-state as long as it is shipped to a FFL. I plan on using USPS because I've read that it is less expensive compared to FedEx or UPS. Does anyone know packaging requirements for such shipments? I was planning on shipping it in a hard plastic rifle case with extra packing in the interior to protect the rifle and then basically secure the case shut with packing tape. Or will the case have to go inside a cardboard box?

Is anyone experienced shipping long guns?
