Thanks for the replies.
How recent is the FedEx and UPS info?
I ask because about 2 years or so ago FedEx & UPS stopped doing shipments involving individuals, either from or to; FFL's only. At least that was my understanding (I could be wrong, but at my age and with my track record (0 wrongs) I find that highly unlikely

).
I would rather pay the smaller charge and ship myself than the $100 or so the FFL's charge to ship a gun. Benelli told me they do not pay for shipping. The shotgun is a Franchi, which is serviced at the Benelli facility in Maryland.
have you asked Benelli how much they charge you for a call tag? I have only done UPS and Fedex it on warrantee guns and through Remington for the H&R barrel program that was years ago but call tag was the easiest Remington charged 25 dollars to send a call tag.
when I mailed rifles I used USPS
here are the rules
I printed them off , took them to the local post master told her what I was doing , she read it about 3 times then said , OK , you will not tell any of my staff what is in the box besides sporting goods or machine parts , it will be taped well , packaged well and will have no emblems or other markings on the outside of the box as to what is inside the box.
send it first class , with tracking and insure it for the replacement value.
I would remove the barrel to make is shorter and wrap both barrel and gun in protective packaging and place in box with no markings indicating it is a gun. tape it very well , have it pre addressed when you get it
