ScottS,
Hopefully you and your buddy are not injured! Remind him to always check the barrel for obstructions! Btw, that is not the approved method for adjusting the choke. A very expensive occurrence, the barrel probably suffered more damage than just the end.
Zuma,
Sounds like the reasons I left Missouri! We get hot and cold here, but usually very dry, so the effect isn't so severe. On the other hand, you can get dehydrated real quick. Doesn't matter where you are thoug, -20 is really cold, and +100 is really hot! Have argent hunt!
