me go boom.

What you saw was more likely the result of a double charge or SEE. More likely the former not the latter. Powder companies have tried for years to get smokeless powder to detonate and haven't been succesful yet. About the only way you can prove what caused the damage is to have it examined by a metalurgist.

4 1050's ??!!!!! At 30,000 rds a year you are bound to have a KABOOM sooner or later.

With 4 1050's, I imagine each one is set up for a single calibre. Do you use bullet feeders on them as well?

nope, I like placing the bullet on by hand, forces me to do that visual check of powder in the case.

anyway gun worked well in practice and at a match except for two rounds that would not chamber during a stage, but they fed flawlessly in the next stage. did have to remove and reinstall the grips to allow the mags to drop out. So it looks like no permanent damage, now I'm ready for the Florida Open next weekend.:dancingbanana:
 
"pressure excursion", not detonation...

While I am sceptical as you are and always suspect an overcharged case first, I suspect that Cliff is using (as I do) a Dillon powder check. That ALMOST rules out a double charge. I have personally had a "Pressure excursion" with a fully compressed charge of slow burning powder in a handgun case. Obviously no possibility of a double charge there, and there was no bore obstruction... It was Ron Reiber from Hodgdon who at that time reminded me that I was using the wrong term. I was still calling it a detonation :) Now I know what to call it, but it DOES happen. I suspect not nearly as much as people claim, of course...

I believe what you are describing is the SEE effect where by an initial ignition of the powder, usually with lighter charges, where the front portion of the powder sets off driving the bullet into the rifling followed by the balance of the powder charge. What in effect happens is the gun reacts the same way as it would with an obstructed barrel and things come apart quickly. I have never experienced same not witnessed an event. Can happen though I am told.

small update, gun worked well through Florida Open and second match down there, and then last weekend at club match, slide stop broke. I expect that was fallout from the kaboom, as it was the original slidestop in the gun. So 3 years and my first broken part. I guess I can join in the CZ chorus now. " the "insert part here" on my CZ broke, it must be a peice of junk!" :) ( for the humour impaired, please note smiley)
 
Glad you are o.k.
I had a practice round go off in similar fashion in my XD-40.
In my case, it wasn't a double or a detonation (Titegroup was made to reduce/eliminate this) but a case that was just a bit out on the base. Wasn't case gauged, and was enough to fire just out of battery.
Case blew out the back and a flash at the chamber.
Gun was fine, I was fine.
 
Tightgroup is actually one of the best known powders for double charges and rather large, dangerous KB's.
