It's not just USPS.... In the last few years, I have had 2 long guns completely broken in half by UPS. One was inbound to me, the other I had shipped. One of them being a somewhat rare Ruger No1 in 6.5x55 Swede that had great wood.
Here are some pics, the third one made me
Ruger really took care of me, completely restocked the rifle, test fired it, etc. The new wood is not quite as nice as the original, but they didn't do me wrong either. The forearm is actually nice, but but stock has less color.
Rifle still shoots sub moa with my handloads.
