The following is the web site address (link above)for a report written on an O/U shotgun blow up. I have followed many threads on trapshooters.com that talked about shotguns blowing up but did not see a picture or see any official report as to why it happened. This includes both pics and report.
I did not post this to start any controversy but to supply you with addional info on what has already been discussed at depth here. Interesting report.

I owned a CG Magnus combo and loved every minute of it and damn sure wouldn't be afraid to shoot one again. They are a very good gun. Better than some want to believe. Every manufacture out there has had a gun blow up for some reason or another. If there are 4-5000 CG guns out there and three of them blew apart with a "RELOAD" then that is not a very big percentage of failure is it.
On a side note. I don't know if one should believe everything you read on the world wide web.

i see this report failed to mention the possibility of a barrel obstruction??? how many times have ya herd a thud on the line and have to tell someone to have a look? this involved a reload... if it was factory than it would be more likely to blame the gun..

well if there is a prob with the guns i am sure we will see more...but the reloading factor still weighs heavy on me as far as failure..not saying that it isn't possible to have gun failure!! just that the only catastrophic failure brought forth so far have been using reloads...

the just I get from this report is a poor solder joint between the barrel and mono block.

To me, the thing is it always seems to involve reloaded ammo. I noticed he was using "AA hulls unibody". I don't know exactly which hull they are refering to as unibody. If he had the newer AA hulls with the glued in base wad, this starts an all new theory again. Could be hull not gun? On the other hand, it would stir enough doubt to me that I would have to think twice before buying a CG gun right now. Heck, you guys got me scared to touch my Krieghoff! (Somebody said they blow up too)
Those injuries sure looked bad, wouldn't want that to happen to me.

This is probably the most complete investigative report on a shotgun blowing up as any of us will ever see. I also noted that all those involved with the investigation are more than qualified to make, and come to, the conclusions that were reached. Much more so than any of us, I'm sure. Based on what was presented, I will stay as far away from a CG as I can get. While I feel that Gary, (Mr. Charles) has some valid points to consider, all indicators point to a faulty gun problem. There is enough simalarity between the guns that have blown up, and the location of the blow ups, to warrant more investigation into the way the CG guns are made. I would think that, at this point, armed with this information, there would be a lot of CG guns going back to the mfgr. for a refund. I can already see a class action suit being considered for those that don't get satisfaction from CG if the problem continues. Either way, this does not bode well for CG's reputation as a safe shotgun, nor for the company's sales in the near future.... Just my observation.... Dan Thome (Trap2)

As a side note, it seems all too easy to blame faulty reloads for these incidents. Obviousley, those that believe this theory have not read Bruce Bowens report on what it would take to produce a reload that would cause this type of damage. During ALL his testing, trying to make a reload that would actually blow up a shotgun, he found it could not be accomplished. IF these reloads were, indeed, a double charge of powder, ANY modern, well made, shotgun should be able to handle such a charge without suffering the destruction noted in this report. Since there was no indication on any barrel blockage, please explain to me how a reload, double charged or not, could do this to a receiver unless it were defective? I just fail to see how a reload, loaded on a MEC, PW, Pacific, Spolar, Dillon, RCBS, etc. could be responsible, nor could it be the loader itself. After all, any loader will only do what it is programmed to do. Do you REALLY think a PW would mysteriously change it's powder or shot drops just out of the blue?..... It wasn't a faulty reload, nor was it the loader the load was made on that caused this type of destruction. I will have to take Bruce Bowens findings as accurate, as he has both the facilities and the knowledge to determine what a reload will, or will not, do.... Again, just my observation...

rhymeswithorange... If I were presented with a detailed, comprehensive report like this one on the K80 guns that blew up, I would say yes. However, I don't have that kind of factual information at my disposal like I do this one on the CG incidents. With that in mind, I remain concerned, but not convinced, that there may be a problem with the K80 as well... Dan Thome (Trap2)

Also the maximum load listed in the 2008 Hodgdon Manual lists 19.7 grains of clays with the WT12SL wad. The load mentioned in the report rated at 10,000 psi is for the WAA12L wad(page 53 of manual). This would seem to be an error in the report. HMB
