You're a good man, MIke Irwin, to have added that post with the pic of a reloading mistake...I've had a similar experience but with far less spectacular results...it only takes one moment's distraction to wreck a gun or worse. In my instance, a half grain over with Win 231 in 9mm blew a chunk out of the unsupported portion of the case, and I felt the Pachmeyer rubber grips bulge in my hand...no damage to the gun, a Colt Commander, but it re-oriented my loading practices. Like you, I saved the ruptured case, then framed it and it's mounted prominently on the wall above my handgun presses.
As to loading for someone else...I don't do it either...but I have allowed selected friends to use my equipment to load their own under my supervision. But even that can be probably be used against me by some SH lawyer bent on a windfall settlement. And too, my homeowner's ins. would probably not cover me.
It's a litigious society we live in...one that we built ourselves, since we've allowed the politicians and lawyers to make it so. And to those who claim anyone can sue but the case has to have merit...I'd say that while the court system cranks out an opinion, you'll go broke defending yourself...
Cherish our flag, honor it, defend what it stands for or get the hell out. Our Freedoms are not free, they've been paid for many times over by heros in uniform. Far better men than I, died that we could be FREE.
