I've used all three major shippers without issue. I've been told, should an insurance claim arise, UPS is the best with which to work. Pack well, insure, and photograph the packing process, both to verify proper packing, and to identify the item. Be aware that most insurance payments are based on "market value", which will include a depreciation deduction, it's not replacement value, so buying more insurance doesn't help. None of my local independent UPS stores will accept air rifles, it must go to a UPS hub. And that is within their operating instructions. One of the local owners showed me in his operating manual that air guns are specifically prohibited. I'll offer one tip. If you open an account with any of the shippers, you can then pay and print your shipping label at home, slap it on and drop it off, easy. One glitch, with USPS I haven't found a way to buy insurance from home through my account, it directs me to the post office.
