Yes, you can ship an item to yourself from one residence to another. He can be the shipper and receiver.
Pretty hard to ship from yourself when you are in another state...
No it isn't. I've done it several times when I need to get stuff from property I own in CO to where I now live in TX. Nobody looks at the names.
Advocating to commit a gun crime on the internet is always interesting...
Nobody is advocating committing a crime. You can even send a firearm through the mail to get work done on it. No FFL required if it is not changing hands permanently. You can box up a gun, insure it and send it. Nothing illegal about it.
Sorry, but you are incorrect on several points relating to the OP's question.
A person may ship a long gun from himself to himself either going from or returning home, no problem. In this case you are advocating the legality of one person shipping a long gun to another. It is illegal for a nonlicensee to do that. Nothing says anything about changing hands and in point of fact there is a change of hands if one person has something in his hands and sends it to another. Some states are enacting rules to make it illegal to loan a gun to another.
I have said nothing about probability of getting caught as that is an entirely different question. It is illegal.
