Texar2,
Sorry that happened. File a claim as quickly as possible to get the process started. It might show up. I had packages shipped that the usps told me were never shipped until a really sweet elderly neighbor left a note on my mail box saying she has 6 heavy boxes that the post office had misdelivered over a week ago and they would not come pick them up. And she was not strong enough to lift even one herself.
Finally with note in hand I spoke again to the post master who then seemed to blame it on the neighbor lady. So, eventually, my packages did make it to me.
While I have no proof of my following statement my experiences are that NEVER, NEVER, NEVER put anything that sounds remotely like firearms related names on a USPS package. The insurance, I am convinced, is just another revenue source for them and I have never had any luck with that. After years of shipping packages with expensive items I have given up on the postal service.
Next time go with UPS....got my fingers crossed for you
