I've read a lot lately about people having trouble with UPS and even others when it comes to shipping firearms or related items.
I don't know if it's the part of the country or what but I always go to the main terminal to ship and never to a "UPS Store".
I've never had a single problem and have always described the item as it really is and insure it for whatever I want. I figure if there's a problem and I file a claim for a $1500 action or a $6,000 gun then that's what I want them looking for when the truck wrecks.

The lady always is friendly and never bats an eye as I've shipped barrels, bolts, bullets, optics, complete firearms and a lot of other firearm/shooting related items and she just smiles and takes care of it.
I shipped one package to Kirby and insured it for $6,000.00 and it was no problem. Just fill out the info on their computer terminal, print the label and hand it to her and in about a minute or less she has done everything, I've paid, she takes the package and I go home a happy little camper.
I've shipped and received so many guns, related parts as well as big orders of powder and or bullets that my wife thinks the Homeland Security people are gonna come visit us and never have had a problem so I guess I've been lucky from what I've read.
