And I didn't get back to it today.  After they got done planting traps I 
went to get one of my BP rifles I had sent back as the barrel was damaged 
and I was having trouble hitting the same wall of the barn I had aimed at 
while I was inside the barn.

This was about a 5 year old TC Omega 50 cal.  And it blew me away when it 
came back no charge, I was expecting about a $400 bill for a fresh SS 
barrel and would have dropped the card in a heartbeat. Thompson Center, now 
a part of Smith & Wesson, really does stand behind their stuff, even if it 
was the idiot owner that mucked it up, which it was 100% my fault.  That 
says a lot to me.

Now I need some decent weather for a trip to the range, I need some trigger 
time. ;-)
