Eightbore is right on with the 2pc AAHS hull,seems no one mentioned the possibility over there.
Nevertheless,the gun should have held better than it did if that
sort of obstruction was the cause.
I mean,look at it...its demolished.

It's not an obstruction. It's a chamber explosion.

We have seen a few of these recently, and others on other boards have mentioned intentional tests to reproduce this sort of thing with double charges of either shot or powder. The pressure never gets high enough to grenade the chamber like we see here.

I have a theory. How about a defective primer?

Suppose the primer provides a small spark, not the powder saturating flame it's supposed to. I've heard of 'detonation' effects in rifles when the powder isn't ignited correctly, and then it all burns at once when a critical temperature is finally reached.

Could this be what is happening? I'm aware of a DT-10 that was chamber blown with factory shells... perhaps primer manufacture is to blame?

I would like to apologize to all on this board for my getting the oranges mixed with the apples. I should have stated that in a statement that CG made they implied that a AA reload,loaded on a PW loader could have been the cause of the blow up.

I assume that lovely report was paid for with taxpayer dollars?

Sounds like we may never know what a scientific examination of the gun would reveal. I didn't read the range report, but from what you guys have surmized, it isn't worth the time to read.

I've given some thought to buying CG guns several times over the yrs. This event wouldn't influence that decision.

GregSy, the report was prepared by the members-RSOs at the club. The club does not have anything to do with the Federal Government except that they lease the ground from the Federal Government and want to avoid the possibility of losing that lease. I have been a member of that club and understand what is going on. The Quantico report is not very technical or fact finding, but it takes pressure off the club and its range officers.

How come you guys blow so many guns of various makes into thousands of pieces? We hardly have any at all this side of the pond.
Maybe it's because you reload more? Maybe that's the problem?

We shoot a hell of a lot more.

And... the pressure is on the ammo and component makers to keep prices down.

We have been handloading since the beginning over here. Handloaded ammo was all we had at first, our gunmakers did not supply cartridges. It's a tradition here, and it's not going to change.

What has changed is the near universal use of progressive loaders, in the search for speed and economy. And... the huge selection of powders and components in more normal times which we hope return soon.

Undoubtedly, some accidents have been caused by incorrectly assembled handloads... but... this current trend of chamber blown QUALITY guns seems to point to something more sinister.

Personally, I'd like to see a sample of primers large enough to be statistically significant subjected to independent testing.

I wonder how close the serial numbers were of the blown guns?
There were 3 this year, I think.

Detonation would seem to be the possibility some would accept since most posters don't feel that a normal overload would destroy a gun. Has anyone heard of a testing program for detonation, especially detonation caused by a primer in a powder charge?
