Priority mail and they will pay a claim because it is legal to ship long guns through them
From personal experience - bullchit...
So you have had them turn you down because it was a firearm?
No. I had them turn down claims because they said it wasn’t adequately packaged - when it was obvious from the damage to the package that it could have been in a vault and it wouldn’t have mattered. Their insurance is a joke - good luck getting them to pay a claim.
