RimX receiver

[F Class John]

When you say fighting it, how so?

I know it sounds weird but for whatever reason, I wasn't smooth with the cycling on it. Something about me and it together was jerky (stutter) and other people who shot it didn't have that issue. I don't know, I know it's a good gun and it's shot well for other, just not me and that's ok. I don't have any negative stuff to say about Vudoos, just that it wasn't for me. To be fair I had the same issue with the B14R. I thought it was a 'PRS full size mag' issue since I ran the CZ so well, but then I got the Rimx and had no issues.

Okay fair enough. My shooting partner can’t run a vudoo either. I was more so curious if it was similar reasons. It is lol. I noticed after running all 3 that while I have the most experience with the vudoo so I run it well it does has different feel to it in comparison to the deuce or rimx. Little hard to explain but on the forward throw of both the deuce and rimx it feels as though they glide around the corner and fall into battery. The vudoo feels as those the corner is a true 90* and you have to hit a hard wall before dropping the bolt down almost like 2 steps versus 1 continuous motion of the rimx and deuce. Step 1 push bolt all the way forward, step 2 drop bolt into battery. I hope that makes sense.

Im curious while this rimx thread is going, has anyone played with barrel torque and if it has shown effect on accuracy. Recommend from zermatt is 30-70lbs. I read somewhere a lot of smiths recommend around 40-50lbs mark for rimx. So has anyone tested different ft/lbs on there barrel and found it had an effect on accuracy

Have a cpl RimX prs rigs and have put together a half dozen. As far as I am concerned they are the smoothest actions out there right now. Adjustable mags are the best out there. I am not in love with the static extractor and it has cost me some points here and there but overall if you get the mags set up well they run.
Treat yourself to one and I doubt you ever regret it.

I test every RimX prefit I do for accuracy on a proven setup. When I first started with them I was trying for a more efficient way because of the time it takes. I first tried snapping them on. That was not consistent. I really don’t see any difference as long as the threads are taken up. 40-50 lbs is a good number.

I have never thought of trying barrel torque adjustment. Interesting idea.
I have played with the headspace and they seem to shoot better with lapua/sk with a tighter headspace than the supplied headspace gauge. I modified their headspace gauge and now use this exclusively. I dont remember how much but I think about .005 less than my original (3 or 4 years ago) supplied. Very good primer strikes.
On both of my mcmillans the sweet spot on action screws seems to be 45-48 inch# with my torque wrench. My wrench has not been calibrated for 30 years and I only use it for action screws so it may not be exact.
I am personally convinced 24-26" barrels are more accurate across the spectrum of different yardage from 50-300. This may be in my head as I have seen pretty impressive groups with shorter barrels also but there seems to be an edge at distance.
Depending on how you intend to use them the reamer needs to have at least some bullet engagement of the rifling. My original was an anchutz reamer that I sent back and had reground to .100-.120ish bullet engagement on C-X and the bulk of the SK line. The set back and the tighter headspace cut my ES by a lot but I will admit that was on probably two test subjects and I never went any further.
The first and second guns I built were both recut and reset headspace with much improved numbers and accuracy. I have heard of every combo under the sun on the 700 clones and it seems like a lot of them shoot very well so who knows if I am just impressing myself with my findings. I have seen some incredibly accurate factory CZs out there so who knows on these cantankerous things. Ammo selection and velocity probably have more effect than all of the little tweaks we try to increase accuracy.

I'd built myself several Vudoo V22 repeaters by the time that Zermatt brought the RimX to market. Admittedly, I'm a Vudoo fanboy, but not without good reason - I've had a good working relationship with both Mike Bush and Paul Parrot and his wife Jill, and the customer service from Vudoo has been excellent & pleasant from the beginning.

I did buy myself a RimX action, more out of curiosity than need, but also because I'd built myself five custom PRS-style rifles on Bighorn actions, along with several more for customers, and have always liked those actions and Zermatt's CS after they took over production of the Bighorns.

I do like the RimX magazine, but not the price - $125 - especially when compared to the poly 10rd V22 mags at $35 when purchased in 3-mag packages. No doubt the new Vudoo 10, 12, & 15rd aluminum mags will be at least as expensive as the RimX, and even though I have four V22 repeaters, I don't intend to replace my poly mags with the new aluminum ones. I've learned how to load the poly mags so as to avoid feeding problems, so will probably just buy one or two of the new12 or 15rd mags for those match courses where the extra capacity would be an advantage. No doubt the RimX magazine's excellent features have made very good impressions on a lot of 22RF PRS shooters - one wonders what the situation would be if Vudoo had come out with their new & improved aluminum mags from the get-go?

Here's a shot of my V22 repeaters & single RimX, from the top down - the V22s date from 2017 to last year when I bought the Three-60 action: sporter in Manners EH2 w/22" Krieger #4; 1st action I bought, w/Krieger 22" sendero with Harrells tuner in Manners PRS1T; only one I've bought as a bbl'd action, w/22" Bartlein Kukri in PRS1T; Three-60 w/23" Krieger sendero with Pro-X tuner in Manners PRS1T; and the RimX w/22" Green Mountain in Keystone's sport Palma contour in yet another PRS1T. I recently re-barreled the RimX with a 21" Bartlein in sendero contour, and will be listing it for sale. The little sporter has a Jewell HVR trigger, all the others have Trigger Tech Diamonds - never had an issue with any of these triggers.

I "snapped" my barrel on, so it is little more than hand tight. The reamer was a "Nevius" chamber from PTG and I set it to have approximately .040" engraving (Lapua CX). 26" barrel. The matches we shoot at our local club are 40 shots (10 on each of 4 targets), 1" 10-ring, .5" X-ring at 100 yds. This gun currently holds the club record with 398-22X. I have no doubt it would shoot cleans if the shooter was more talented.

I remember many years ago I was at the old Bighorn/Zermatt shop here in Colorado talking with the owner.

I was asking him to consider making a 40X type action. This was pre Vudoo and before Bighorn became Zermatt.

He said nobody would buy one.

I was asking him to consider making a 40X type action...He said nobody would buy one.

I'm sure at the time that was pretty good logic especially if it was pre-2000 but boy am I glad that sentiment has changed. I was in the gun business most of the 90's at one of the largest LGS in the country and back then a kick-ass .22lr was often considered a 10/22 with a laminated stock, VQ trigger and a sexy stainless bull barrel and even at that they weren't flying off the shelf or nearly as accurate as what's out there now (or was out there like a 40x). Then again we often sold standard 10/22s for $99 on sale so building a custom one was often less than $500 by the time you were done.

I have no doubt that pricing, availability and other factors not to mention Covid have led to a perfect storm of 22lr blowing up over the past 3-5 years. I know even at my club the ole' timers keep saying they're shocked by the sudden spike in everyone showing up with tack driving 22s. In the end I think it's great for the sport. Heck I've even seen a guy show up with a repeater airgun (probably cost as much as my RimX) and spank a bunch of people. It's a whole new world these days.
