RE: $1600 worth of parts...
day-um![:-] Glad I can't even afford to look at one of those bad boys. I think with a hoss like that, I'd be looking to shoot 2219's or something instead of carbon. Of course, it wouldn't be blazing those bolts downrange at over 400 fps, but at least they wouldn't explode when you pull the trigger.
Suppose it's possible the bolt had an undiscovered crack and the shot finished it off?
