The Kalispell cases are very good...but NOT "UPS proof". A friend ordered a custom Highwall from Meacham in Idaho, several years ago. Pretty, expensive, rifle...shipped to him in a Kalispell aluminum guncase. He heard his doorbell ring, heard a "thump", and just caught the driver before he had left the driveway, after tossing his rifle case up onto the stoop of his suburban Chicago home. The case was bent in a shallow "U", with tire tracks across the middle...he said it looked as if they had laid the case on a curb, and drove a forklift over it repeatedly. He refused to accept the shipment and made the driver take the case back, and Meacham's called him in a few days to say the gun had to be completely replaced, because UPS managed to not only break the stock, but broke the tangs from the receiver as well.
I MAIL my guns, US Mail, Registered. Never a problem...(knock on wood!).
