I had a G grade I was sending out to be restored several years back. UPS broke the stock at the wrist. The trials and tribulations are recorded in the archives of the old forum if you want to see what I did to recover my damages. It's not easy and takes time but can be done. Initially UPS told me the insurance was void because they have a policy against shipping guns.

I have shipped long guns via USPS and UPS both without any issues. Just fortunate I suppose and I think the one thing that can be done to 'try' to mitigate any potential damage is to wrap these guns up extremely well with all manner of cushioning material (bubble wrap) in a container that is difficult to bend or break. Then say a good prayer as the mail clerk takes your package.

Julia got our UPS store to show her how to pack guns and (knock on wood) that has worked so far. Some of the people we ship to have a hard time getting the guns out is the only minor issue.

I just received a fine old Winchester M94 from UPS. The sender had made a wooden shipping crate, lined it with foam if I recall and put the gun in a sleeve. It came through no problem. The shipping carton was so well done I saved it just in case I'll need to recycle it sometime.
