I agree its about the mag. I think in my MPA Chassis I might have to make ensure the mag goes in exactly the same every time...

A word to the wise problem resolved !
I had a FTF in my RIMX the other day during a rapid fire session 1st one in 2000 rounds. Normally I clean every session the day before I did not do this , I set up to shoot about 15 rounds down the shell jumped the bolt face. Wonder it didnt fire as fast as I was cycling the problem! Well I had noticed a little bit of wax on the breech face of barrel at the end of sessions from blow back on port side. Right in line with the hardened plate ie.tensioner or extractor what ever they call it. The wax had packed under this allowing no room for the minamal edge to capture the case and retain it during cycle. The fix pulled bolt, with a curved micro plastic pick I cleaned this out we were back in business thought the edge suffered some damage from the hard cycle it still works and a new part is in the works. Clean both sides of bolt face regular to stop this from happening. I attacked photo to show damaged tensioner edge.

So am I reading this correct that a build up of wax under an edge has caused enough damage to a part warranting replacement of that part?
I think getting the rim partially under it and trying close the bolt on it could damage it.
Mine does the same thing run the bolt fast it works. Otherwise the rim jumps up infront of the bolt. I have the mags set as high as I can. My first extractor chipped around 3000 rounds. It still extracted fine just ejected back into the action. I found the Vudoo mags with the black follower feed best.
Got the new part tonight 2 day delivery CUSTOMER SERVICE ! Now just find some different ammo to finish proving the Proof barrel another barrel shipped today, but I have to try the .224 rimfire 1st ,wind gust were up to 40 mph today and I only have 20 55gr rounds loaded will see.
Got the new extractor installed ran a mix of Midas,R50,Tenex Match and SK HV slow and fast cycles no FTF or zero change. A proven statement to precision machining, I finalized the 18" all stainless Proof barrel today I'll pull it and rack it with test data. Tomorrow will start running test on the .224 black hole with 55 fmj bullets.
I shot a Kraft challenge with my RimX a few weeks back. That might be the most insightful 12 round drill I've ever shot. Super fun to do and I was surprised with my results given that I rarely shoot positional. I really want to work on it and see if I can get down below 1 MOA for my baseline targets before I start adding some speed requirements to them.
Then call zermatt and ask like i said if id waited 20 weeks and other places had it id be canceling unless you got some awesome deal
That's a bummer you've had to wait that long. I agree, I think a call to Zermatt would be in order. I would think they would want to get an action into your hands having waited that long. I am also curious what wait time they are quoting, and how many they are producing currently. I messaged them through the website/email first of the week, didn't hear anything back. (I should've attempted a call) I saw that Altus had them so I went ahead and ordered from Altus and it is supposed to arrive tomorrow. Looking forward to getting a barrel on it and see how it does.
Have had mine for a week as of today, 1200 rounds so far, everything is great but every now and then it won’t kick the fired case out. Just falls on top of the magazine. Thoughts?
Run the bolt back harder/faster!! I was getting the same thing when changing positions on a stage. I was not running the bolt back all the way like I do when shooting from one round to another. I was just opening the bolt and half heartily running the bolt then moving to the next position on a stage. When I went to feed another round it would have not ejected the spend brass. Hope this helps!!
This happened to me too at a match last Sunday. 3 times actually. Lost a lot of points to this. Of course I assume shooter error in my case, what could only be "short stroking" the bolt? Not sure yet because it did not happen during practice. Please share if you find out, so will I.
I agree Bis, I’m coming off shooting an rpr since they’ve been around. I really think majority of it is me just not getting after the bolt! I’ll keep proofing my dope this week when I can, hoping to make it to a match Saturday and see what happens. I took it this past weekend to a small NRL club and had it happen twice but I can hear it rattle in there so I just dropped mag, reinserted and kept on going. I’ll keep updating what I figure out! Thanks guys!
I just noticed Rimdenter's picture on this page, post #1710. If I recall correctly, my extractor edge looks like his in the picture, will check tonight at home. If so I'll get a new one and this should take care of the issue.
I wish I had took pics of the slight mods I made on my tensioner. I totally disassembled the bolt , the tensioner's are made on a high end laser. I could see directional wash as the cut changed directions. I know this because I ran a Cincinnati laser , when you cut any type of higher carbon steel the edge surface becomes hard. I removed a small of material on the inboard shoulder and rear with a diamond dremel bit allowing the tensioner to close app
.008 more gripping the shell firmer taking care of this slow extraction problem. Since its gripping the casing tighter it doesn't throw the spent casing as far though. You have to be careful doing this, if your not running a tight spec match chamber and the extractor is alittle off it will and can allocate the case off center up to 1/2 the chamber condition. I saw no accuracy loss but max on chamber is .0008 over unifired rounds.
I’ve put a few different types of SK Ammo in my RIM X. Every type has 1 out of every 5-6 rounds get stuck in the chamber and bolt will not close. Proof CF 20” prefit on the action. Picked up from Gunware late last year. Thoughts fellas?!
Does it happen with a particular mag or all of them?? If it is all of them I suspect you're short stroking the bolt and pushing the round into the chamber without the rim of the case being under the extractor.
the rim isn't getting up into the extractor. double check your mag height
Manners T2A inletted for an Impact with my RimX in it. Only thing I had to do was sand a small spot that the bolt was rubbing on.
Any one have experience with Bison Tactical barrels? The test targets they show are impressive plus the accuracy guarantee and test target furnished is hard to beat. I have a Krieger barrel being chambered by Jonathan Elrod who does their barrels. He has a long history of 22rf work and is recommending a modified JGS match reamer that has performed very well in his testing. After having the GM barrel I got with my action finally up and running, I am looking forward to the next step.
