I have a Kimber 84M Light Tactical Police .308 and im wondering if anyone can tell me the purpose of the strange grooves in the chamber. It actually prints these grooves on the spent case after firing. You can feel them if you drag your finger nail across it. And they're even noticeable after resizing the brass. The rifle is a sub moa shooter all day, but these grooves in the chamber have me stumped. The only thing I could think is that they would aid extraction.
Kimber 84 M LTP strange grooves in chamber

Reminds me of the G3 H&K. Definitely looks intentional.
ETA- call kimber and ask them why you have a fluted chamber and if its intentional.

I know this is an older 84 LTP...... it was kind of a New Old Stock rifle I got a smoking deal on it from a gun shop that was closing down. It was the first generation I believe, you can tell because it's not ambidextrous at all, the stock is definitely set up for a right-handed shooter only. The newer ones are more Lefty friendlyOddly the Kimber site mentions nothing about it. Maybe LaRue is making their barrels
No idea if the brass will hold up. Ive only resized it once so far. I checked on kimber's website and I can't send them a message via email, but I will try calling them tomorrow.
It does remind me of the brass that came out of my HK-91. The fluting in the H&K was somewhat more pronounced. It's been a long time since the H&K for me so someone else here probably has a good photo of what the H&K does to brass.
@DTOM Tim , sorry about the bad joke but someone had to do it. It's a thing here

The fluting was placed in the chamber to ease extraction. At least you don't have to put up with the horrendous dents that the G3 can put in a spent case .

)I bought this last week so the Kimber will be on the backburner for a while anyway
So I have a call into Kimber. So far they have no answer for me. I emailed them some pictures and im waiting to hear back.
That is chatter from running lathe spindle rpm and feed rate too fast for the reamer. There is nothing you can do about it, it could be polished out but over polishing a chamber leads to more problems.
That sucks. I would expect better QC considering the MSRP of this rifle. Would it have any negative effects on the rifle or brass?
So being that it's a $1,300 rifle, and that seems like pretty piss-poor quality control if it was unintentional, do you think it's worth complaining about it to Kimber? I bought it brand-new a couple years ago but just started working with it a couple months ago
You should see what they have to say and if they do anything about it. You would have to send it back for warranty work. Then you'll get a better looking chamber and possibly a barrel that doesn't shoot as good. So it could be a toss up.
