Agree 100%
Incredibly clean break and when my safety jammed, they replaced the trigger. The older ones had ball bearings and have been replaced by rollers, much smoother operation. Mine has functioned flawlessly since I received it. Their collaboration with the clone action builders to do the design and function really paid off.

Going to test barrel #3 this afternoon and shoot a match tomorrow with it. Don’t have time to lot test. It will be what it will be today and tomorrow. 20” Keystone GM straight 1.20” with the Eachus chamber. It chambers rounds smoothly (so far) and can easily extract no problems. There are definite land marks on the driving band.
I’m going to be using a lot of SK RM I have. I will update with my thoughts later.

I'm looking at a Keystone from John. Do you know if the leade is 1.5 or 2 degree? Great pictures. Thanks
Looking forward to the test results. They are excellent barrels.

The only good things I have read about 1.5 are from Kevin Nevius and he feels the 1.5 is pretty Lapua specific and 2 works for pretty much everything. I think that is pretty much verified seeing the results your chamber showed in your barrel tests.

What will be interesting for me is that I’ve become more of an Eley shooter. I’ve seen how I can group with my capabilities and curious to see how this chamber does with Eley.

The Keystone GM with the Eachus chamber is an absolute hammer. Got to the range this afternoon and went to work. I didn’t do any special barrel seasoning routine or break-in. IMO if the barrel can’t shoot it can’t shoot. I shouldn’t have to pump 600 rounds through it first. The groups above are are within the first 100 rounds. They are not cherry picked. I shot a 5 round group and moved onto the new ammo. Again, no fouler shots in between new ammo. I went to town. The CX group was within the first 15. I shit you not.. Sorry 6x and 10x guys. I know the capability is there to shoot small groups with good ammo. I’m a grid convert and dialed in that way at the end of the session. Whatever batch the barrel blank came from its awesome.

RimX is amazing. 22" GM barrel 1.20" straight from Keystone. no idea which chamber but it shoots great with SK RM. 🤣
Amazing indeed. The lot of RM I have shot like shit out of my other barrel. It was a laser with the GM today. I was getting avg of 1082 fps (15rds) and SD of 5. Sadly I’m on my last few boxes.

how long is your barrel? I was at avg 1056fps with SD of around 8 at a match last weekend.

I was having feeding issues with my t1x and picked up the rimx with help from a cert that I picked up off a prize table last year. zero regrets. feeds like a dream.

Hi Guys,

My outing in the back yard last week, wanted to try some different kinds of ammo with this Rim-X and Keystone GM barrel, results below. I probably shouldn't have been shooting on this day because a storm was approaching and the winds where swirling, but when ya have the itch ya got to shoot! :D This photo of the rifle just has the thread protector installed, but I shot these with my Thumderbeast Ultra 9 can installed, it's so quiet, bullet impacting the bullet trap is louder then the report..... LOL

Here we go....... I didn't clean the barrel between ammo, just loaded up the next kind of ammo and shot it.

Target 1 = SK STD PLUS
Target 2 = NORMA TAC 22
Target 3 = SK SEMI AUTO
Target 4 = SK BIATHLON SPORT
Target 5 = SK RIFLE MATCH
Target 6 = SK LONG RANGE MATCH
Target 7 = CENTER -X
Target 8 = MIDAS +
Target 9 = X-ACT
Target 10 = ELEY TARGET
Target 11 = PMC SCOREMASTER

My action and barrel came in on Thurs, put it together yesterday and managed to hit the range briefly in between storms(mostly). Could only shoot 45yds. Was having some extraction issues I chalked up to my unfamiliarity with the system.

Shot my first PRS style match today. Extractor fell out on stage 2. Still had about the same frequency of malfunctions. Maybe 1 in 15 empties would kick back in to the action and lay perfectly on the inside bolt rail. Wasted a lot of time stripping mags out, so I could remove it. Wasted more time because I'd lose a round clearing the malfunctions. All of the stages were 10-12 rounds. (guy at the match cheapskate precision, I think, sold me some +5's and a loader that he makes. After the match of course, lol.)

It was my first match of this sort. I played in action pistol and 3 gun back in the day, so reading stages and shooting off random stuff came pretty easy, although I know I got away with some stuff I wouldn't with a centerfire. If I could guess the dope, I got hits. Having never shot a rimfire past 50yds, I feel like I did ok. Winds were crap. 15-30 mph full value. The built the match with the wind in mind thankfully. Most targets were under 100yds.

Gotta call Zermatt on Monday. Think there is a spring, and maybe a detent that I'm missing now. No fault to them, this was a used action, and I threw together in haste. I'll go back and actually learn the system and go through it now that I have some time. Then a month to get ready for the next one!

My 12yo son shot a couple stages and loved it. Have a 455 in the safe for him. I checked out a NRL Bushnell model and was impressed. May drop than on it instead of the squirell oreinted glass it's wearing.

When I bought my action second hand I ordered all the spare parts listed on their website. Nice to have them just in case. And the postage will be the same. @serevince
Same problem with rounds ejecting on to left side of action I had. The round is probably ejecting off of the magazine. It is too high. Needs lowered just a little. Very small movement to adjust.
I pulled the firing pin to make it safe when using live rounds for adjustment. You will be able to slowly eject round and see it hit magazine.

Also watch for the tensioner - I was having weak ejection and then I figured out the tensioner screw just needed to be re-torque and now ejects fine. I think it was also causing a failure to feed because ever since I torque it, I haven’t had an issue feeding in 500 rounds.

@serevince Before every match I check the following:
-Extractor on bolt head. I make sure the 1/16” sized set screw is snug. FYI there’s no spring behind it.
-Tensioner claw. I make sure it doesn’t look funky or bent in any weird way. The tiny claw is held in place by a spring and detent (pressure).
-Ejector. I make sure it doesn’t wiggle by pushing on it with my finger. Before putting the action in my chassis I added a drop of purple loctite to the screw that holds it on and snugged it up. It’s not really super accessible once the action is installed. There’s no spring here either. It’s a fixed object.

New barrel match report..
The new Keystone GM axle performed very well yesterday. We had engagements out to 192y and a mover stage at 165. Zero issues running SKRM. Every round fed, fired, and extracted. My dope was pretty much dialed in. The only limiting factor was the guy pressing the trigger.. me. The match was challenging and a few stages had you thinking a bit on what position would be best. I ended up being in a 3 way tie for 14th. A few stages F’ed me pretty good.
Our squad was solid and the match winner was also in the squad shooting a RimX.

So I just around to digging back into this. I called Zermatt and was shocked that a real person picked up and was knowledgeable and helpful. I was waiting for a automated directory, and it caught me off guard, lol. A new extractor and tensioner are on the way.

In the mean time I replaced the extractor and now it does not eject at all. (I also noted my extractor appears to be the newer material). I came back here and re-read and it looks like I am missing some key knowledge?

I can ID the extractor, and the tensioner. Both appear to be in good shape.

What and where is the "ejector"?

Think I need to figure out the ejection issues before I tackle mag height tuning. (I can remove the mag and it still does not eject)

The ejector is attached to the action. It’s the “blade” thing poking up. If you peek in the port you can see it.

This thing ran shockingly well despite the idiot behind it leaving out 2 parts critical to extraction and ejection...

I'm going to have a running gun, and a dope at the next match.

Gonna need some news excuses. Damnit

Just got my rimx wanted to disassemble the bolt but I'm having trouble. I've already looked at the videos on how to disassemble the bolt the problem is I cant separate the body from the firing pin assembly. I can twist the fire pin assembly from the body and that's it. The fire pin assembly will not pull apart from the body what am I doing wrong

Made a quick video.. about as far as I typically strip it down to for quick maintenance.

Can you elaborate on what you mean by that? Do you remove the firing pin to dryfire? I always just strayed away from dryfiring rimfire rifles.
The beautiful thing with the rimx is that it is easy to remove the firing pin and dry firing it without the firing pin doesnt damage the action.

Correct. Zermatt recommends you remove the firing pin for dry firing. Last bullet point..

I love the accuracy potential of this barrel. I mean for $400 can’t go wrong at least in my opinion and personal experience. It does what I ask of it and with my capabilities. I calibrated DSF this morning and then walked it out from 100 to almost 400. Fired either 2-3 rounds each target. Winds were low around 2-3 mph L to R.
Again I suck at shooting so I’m not going to bore myself with 6x5 or 10x5’s.

Wow, I am surprised to see the responses here. Between me and my shooting buddies we have 5 RimXs. Only 1 was purchased as a barreled action, and it was also the only one to have a problem. The other 4 have prefits from PVA (don't recommend), straight jacket, and proof. It really isn't hard to put together, and if there is a major issue, whoever made the barrel better stand behind their work.
It is good to see I am not the only one with this experience. My initial order was a barreled action, nothing but problems. I had a local gunsmith who had never even heard of Rimx contact Ray and rechamber it for me after using a 6' bar to get the barrel off the action. Since then, I have had Jelrod (MODACAM) do 4 barrels for me including rechambering (he does Bison Tactical prefits) and they have all functioned flawlessly. He is great to deal with.

I should reach out to Elrod to see what the typical turnaround is. I’m in no rush but I need to check on my Krieger.

I just had him build me a Vudoo and his turnaround time was 3-4 weeks. Other times for my Rimx barrels when he was busy it ran longer. His work is great. You might consider going with a Shilen ratchet. This is the 50 yd test target he sent me. I liked my Krieger, but after seeing the reports of BR shooters going pretty much exclusively with button rifled barrels, I sold it and am going with the Shilen ratchet. The only barrel which is sometimes preferred is the Muellerworks and it looks like they have a 4+ year wait, I have been able to get Shilens quickly, though not from Shilen as am like 2=3 months into their 6-8 month waitlistl

    Depending on the distance you are shooting, the Shilen and Benchmark (small # of grooves) might not be the best application. Some of the research says that higher groove and cut rifling seems to help out with longer distances ~250+ yards. Shilen, Benchmark are both low groove and button rifled.

    I have a Benchmark on my rifle that performs very well close distance. Looking forward to a Krieger for another build to see how it compares at the longer distances.
