Is this the old or new Kemen? There should be a date code on the barrel flat. And a full size close up of the blown breech would be nice.

In the case of the Benelli nova, I was guiding a young guy goose hunting, and it was his first shotgun that he bought.

He put in brand new Winchester 3 1/2 inch BBB’s, and the first shot out of his new gun sounded weird and I thought I saw something fly.

I stopped everything, went over to his layout and looked at his shotgun, and you could see a patch inside the barrel that was missing.

Benelli would do nothing. They said it was the ammunition.

Winchester overnighted a brand new nova barrel to us and we put it into his shotgun. And it worked fine.

Winchester was all about getting those cartridges back.
And no cost to the kid.

But when you are blowing up the strongest part of a mono block shotgun, in 2026, well…

Funny thing is, reloading a 12 gauge these days is a fool‘s errand.

When these guys are making up shotgun shells from World War II reclaimed powders that were designed for rifles, and they think they’re onto something, all I can say is good luck to you.

I’m not saying that in this case it is anything as extreme as that.

Again it’s a pretty expensive lesson and I’m sorry that it happened.

It’s not like Lord Walsingham shooting off his barrels during a hot flurry and a quick exchange.

It’s going to turn out to be a reload where somebody put rifle powder into the cartridge. By accident.

I’m glad no one was hurt, and it’s unfortunate that a reasonably expensive shotgun was destroyed in the event.
I'm just saying- that I always check my barrels when I load my gun to make sure there is no obstruction. Some people don't. That's all I'm saying. smile

Given the number of reported defective factory cartridges in the past few years that would be a likely recommended process. And catching the carts along with blowing the smoke out of the barrels has a definite cool factor.

Last year at the local club we had a member who had 4 bloopers out of a new box of Winchester AA 12 gauge skeet loads (9 shot). Contacted Winchester and they asked for the lot number and sent him a brand new flat. It happens for sure.

Several years ago I was shooting on a squad and one guy had a blooper. I waited for him to stop and clear the barrel and he never did. When he was putting another round in his gun I started hollering for him to stop. There was a wad in the barrel all right that he didn't notice and he had forgotten to listen for one. I was the one who had taught him to shoot and he was shooting with the 686 Silver Pigeon trap gun I had sold him. So, I was always kinda keeping an eye on him.

Engineering something to be foolproof will universally lead to discovery of the ingenuity of fools.

Just to be clear, you're saying that substituting 18 grains of 4895 for 18 grains of 700x is going to blow up a shotgun?

I am saying that home brew reloaders, assume all risks of their stupidity.
the trap shooting world is rife with them, of course the trap shooting world is also littered with blown up Shotguns.

You be the judge.


To cycle back to the original post of this thread, the PSI required to blow up a mono block that is cut from a steel billet that is tested multiple times before it gets near any of the precision work has to have extraordinarily high pressures.
Only so many ways to get there.

Only so many ways to get detonation in a shotgun hull.

The OP hasn’t offered any additional information since the beginning.

Read into that what you want
