Kimber with a bad chamber?

Hi guys. I bought a Kimber 8400 a few years ago in 25/06. It was used and in like-new condition. Its a good shooting gun. However, when you eject a fired casing from the rifle you will notice a ring indented into the casing the whole way around (the casing) just behind the shoulder. I noticed this from the start and didn't like it but called Kimber and they said it was fine.
Recently, I found another problem. Although I had reloaded for it, I had never reloaded a casing fired in the rifle until this past summer. What I found is that none of the casings fired out of that gun will go through a standard full-length resize RCBS reloading die. You get a little over half way through the stroke and then it gets tight and then, really tight, and it simply won't go through the die. It makes no difference whether the casing fired was a reload or factory load, and I have a Remington 700 25/06 and fired casings from it go through the same die with no problem whatsoever. What are your thoughts and/or do you have any experience with this kind of thing? I called Kimber twice and they seem reluctant to do anything. They said I can send it back but they're not guaranteeing anything. It seems to me that the chamber is screwed up in one way or another. Thanks for any input!

Re: Kimber with a bad chamber?

Are you getting excessive noise and recoil? Sounds to me like headspace is not correct. Take it to a gunsmith and have it checked. A simple go/no-go gauge will tell the tale.

Re: Kimber with a bad chamber?

Take a known to be good case. A factory round or a mic'd resized case. Put 4 pieces of scotch tape layered on the head of case. Stand case on head and trim the excess tape off with a razor blade. Once trimmed put case in the gun and try to close. If the bolt closes you have way to much head spacing. Scotch tape is about .002 each. You should have no more than .006 headspacing. More than that and you have safety concerns.

Re: Kimber with a bad chamber?

Well, one sure way to determine the problem(s), make or have a chamber cast made. Its virtually impossible to make any chamber diameter measurements otherwise.

Seeing your die seems to resize brass for your other 25, I kind of suspect the chambering reamer may have been run in a little too deep enlarging the diameter of the body portion of the chamber. That would show up using headspace gauges, the chamber would be longer too.

The ring you speak of at times is result of using a chipped reamer when the chamber was cut. On the other hand being a used rifle its only a guess what the previous owner may shoved in there! If its not affecting extraction its probably nothing more than a visual annoyance.

Unfortunately, since Kimber doesn't seem to be interested in helping you have few options. One sell the rifle informing the new owner of the problems,two, take it to a 'smith with the tools to correct it or three,have it rebarreled.

Either way your going to spend(lose) money.

Re: Kimber with a bad chamber?

First take your gun to a local EXPERT gunsmith and get his opinion and options available to you..He may give you some good advice..

Use your 700 and,as wildbill says,try to get a chamber cast made and measured.

Re: Kimber with a bad chamber?

The guy you need to communicate with is Barry Vanderstouw (pronounced Vanderstow) at Kimber America.

His email is: [email protected]

He is a long-time Kimber employee and is/was located in Montana. Forget about dealing with the people in Yonkers as they are part of the quality problem at Kimber. Barry helped me with a problem I had several years ago with a .338 Federal.

Tell him you want to ship the rifle to him not New York...

Good luck. Your plight is unfortunately not a rare occurrence with Kimber rifles. The internet is full of horror stories about the lack of quality control and guns getting shipped that should never have left their facility...

Re: Kimber with a bad chamber?

The ring around the shoulder sounds like excess headspace (case is stretched by moving forward.) If you see it on factory once fired brass as well, Your sizing die adjustment may be excessive, pushing the shoulder back too far.

BTW, my Kimber 84 in .308 has gone back to Younkers 3 times for problems.

Re: Kimber with a bad chamber?

Several years ago a noted gunwriter tested a Kimber rifle. His story that followed was nothing but love. In his final statement, he said the Kimber was the best copy of the Winchester M70, in fact, he stated " The M70 was never this good". Then they started being returned. Returned for machining errors that a kid in shop class would have found. They are a well made gun in general, but their Q/A and control is abysmal. You either get a good one or a bad one.
