Thread: Case stuck in chamber

Thanks guys. Yes the action was blue printed so sounds like it could be a primary extraction issue. It's not RR prefix so there is a glimmer of hope cos I'm not liking the look of the fix I saw on YouTube.

I'll give the brass a good check over first then pull the scope and check the cam clearance.

RR series were some of the worst offenders from the factory but as mentioned can also be an issue if action has been "trued up"

When you check the cam'ing it take the firing pin out of the bolt. Its quite easy to see if primary extraction is there or not. Is the 280 an AI or std.

The actual fix if that is the issue should be quite straight forward for a competent gunsmith who is good with a tig welder. Sadly I was not so lucky

Do you have any new cases that have not been fired in any firearm yet?

Please, test and compare to what the used&sized cases do with the same loads.

Can you please do me a favour? Measure the neck diameter of a loaded round and also the neck diameter of a fired case?

Thanks Jaco will try all of above, measure and let you know. Luckily I can fire shots out the garage door without upsetting anyone except the misses if I forget to warn her.

Right here we go case dimensions, additionally loaded rounds measure .315 at the neck, chamber is .320.



So first up the new cases. Win brass is definitely a little smaller and consistent down the neck. I've never fired these as only have a few pieces. Norma just has the increase at the base of the neck.

New vs sized again don't see any major issue except maybe the base of the neck and the same for the fired.

I then went about chambering all cases with firing pin removed. All cases chambered very easily with no resistance except a little on the new Win brass so assume the shoulder is a little further forward. Didn't measure this but can if needed. All cases including 10x fired, all extracted but would say only 50% gave positive ejection, the rest came back but still partly in the chamber or sat on mag follower. The fired cases being the worst. A few loaded rounds also chambered easily and extracted but again poor ejection.

Repeated the same test but with firing pin in, all new and sized brass extracted, fired brass 3 of 10 stuck in chamber.

Repeated again on fired brass but pulled trigger 8 of 10 stuck in chamber.

Appreciate you thoughts on this and what to load if needed.

Hi @mikee definitely looks like what's in you video. Cam not contacting. Forgot to take pictures but will do tomorrow.

The Norma case base isn’t getting sized down enough. Ideally you want minimum 0.002” sizing of the base on fired brass. I’m surprised you’re not getting clickers at top of bolt lift.

First port of call is the guy who built it, give him the chance to fix it but not multiple chances like I was stupid enough to do because did not know any better. If he is any good and takes professional pride in a job well done then it will be sorted.

Your reloading will not be to blame, nor will anything else. Its a really really common issue that some suppliers seem to have no clue about.

Yep I think that's the only way to go from here, certainly beyond my expertise. Guess I'm hanging on to the hope I can still use it this roar. Ha could always carry round a cleaning rod.

Just think of it as a muzzle loader?!
Definitely take it back to the gunsmith who did the job so they have the opportunity to diagnose & fix. But I would also share with them what you’ve experienced in trying to diagnose the fault & the known fault in some REM700 actions for lack of primary extraction.

Cheers mate.

Thanks for all the measurements. Your cases as well as the neck thickness has been cleared of suspision.
