Howdy Forum,
I don't have a whole lot of rounds through my KSG but have had problems. Recently sent it back to the factory. Casings were swelling and it was tough to rack out a spent round. The factory replaced the chamber and suggested that I should use high brass to prevent that problem.

Does that sound reasonable. Do others have to use more expensive high brass for shooting? I was just getting good at clays with it, a choke tube and a red dot (blast to shoot). Has anyone else had a chamber go bad? I only shoot factory loads.

Thanks

KR

"Replaced" the chamber? That doesn't sound right, as it would be the barrel replaced. You sure it wasn't "reworked" the chamber?

Swelling is not usually an issue. The main issue with the KSG is the rough surface finish on the chamber causing poor extraction. Usually, its the Parkerized finish in the chamber. Most shotguns don't have a Parkerized finish applied inside the barrel, but the KSG does. It will "shoot out" of the barrel itself, but can cause some sticking issues in the chamber. There are various tried and true methods, both old and new, to clean up a shotshell chamber. The old old way is to get a wooden dowel of almost chamber size, and cut a slit in it. A strip of cloth backed sandpaper gets put in the slit and the dowel is rigged up to spin inside the chamber with the sandpaper in a sort of in/out motion. The new fangled way uses a hone. I'm not sure if maybe a brake cylinder hone might fit, but a specialized hone is made for shotgun chambers. The use is the same, except with the hone you use lots of oil to prevent it from loading up. That's about it really, you hone it out, one way or another, and they're good to go after that. You're only removing the Parkerizing, not really any (or much) metal from the chamber itself. Shotshell chambers are not critical like a rifle chamber would be.

Don't overlook the obvious: A barrel constricted with melted plastic will over-pressure the shells.
Hard as hell to scrub out:

p.s. It's killer on clays with that setup, isn't it?

Any chance you were shooting those Winchester Universal target loads? They are known to do that in lots of guns.

Just got my KSG back from Kel-tec due to feeding problems. Can't wait to shoot this weekend!

We really need a Fluff n Buff sticky for the KSG....

So many folks have issues with chambers. Shotgun chambers are so non critical it can be a home fix, or local fix.

There's one already stickied....look under the FAQ'S.

Yeah, there are reports of issues with the low brass shells. I never had much issues with my ksg. Once i learned the manual of arms, no problems. However, at Fido 16 i did experience a stuck shell with the cheapest low brass range fodder i could find. The spent Shell was stuck in the chamber. We were shooting clays. I let the gun cool off for a few minutes, which may have helped release the stuck shell. But it acted like it was never stuck.
Never had a problem with high brass. And that's what i and the factory recommend.

As a side note, i had the factory "go over" my ksg because i was having issues with a total (non field) strip. They - my words- rebuilt the gun. Replaced the receiver, other parts and gave me a new(ish) serial number. I thought it ran like butter until my failure to extract at Fido's.
