Still waiting for my call to send mine in for the conversion. Going to build a second rimx as well in a lighter config for just playing around and as a backup to the main comp rifle.

Thoughts on it after conversion?

My ModX conversion has over 1K flawless rounds on it now. I have shot it out to 300y and no issues. I run both Vudoo and RimX Mags without any issues as well. I like it way better than when I was a regular RimX. NO need to worry about the bolt bouncing a round ahead of it and having to dig it out with a knife. Side the bolt home and fire the round on target.

My 2 Gen1 Vudoo builds ave been set off in the corner for now. When its time to re test at lapua we will see which of the 3 gets the best groups and shoot them rifle from that point on.

I’m going to send MCR my RimX probably some time in January. I just have to decide which barrel I want to have converted as well.

So did you have new barrels cut after having your ModX conversion? Or did you have your barrel set back and headspace then set? What ammo did you set headspace for? I know headspace for a standard RimX with tensioner is minimum 0.0455" and most shops set it something 0.046-0.0475 which would be excessive if no longer using the stock tensioner.

The whole point of the RimX design was to remove the burden of setting headspace for a certain type of ammo (lapua, Eley, etc.) because by RimX design, the case was held firm against the bolt face so the round couldn't move during ignition. This is what allowed the prefit precision 22LR market.

When you remove that design, your back to the age old 22LR method of having to set your headspace for the ammo you planned to shoot unless ultimate accuracy and ignition isnt a concern. Your now essentially shooting a Vudoo once you do this mod.

For example, before the RimX, using the age old method of chambering precision rimfires, if you were shooting Eley you set headspace to 0.0385-0.039" headspace vs Lapua you set 0.041-0.043" headspace...

I had new barrels cut. I have a 13t MW at 23' and a 25" 16t Brux.

100% understand that im essentially shooting a Vudoo. It is a Vudoo with a better ignition system and a flawless magazine. I do use a Vudoo mag for a 10 round mag and RimX mags for my extended magazines.

Gotcha, that makes sense. What did you have headspace set to for the 2 new barrels? Are you now only buying and shooting ammo for the headspace you set?

Defender32 · Dec 26, 2024

Johnathan set it based off the Lapua I sent him. It has been great with all Lapua & SK so far.

littlepod · Dec 26, 2024

I haven't gotten my ModX yet, but you can also just get your Vudoo bolt modified to take in bolt shims, then you can add a shim to cover the headspacing for Eley. My goal with the ModX was basically to shoot a Vudoo with RimX mags

Gotcha so probably something in that 0.041" - 0.043" range for Lapua.

How is the brux shooting compared to your other barrels?

I like my Brux better than any barrel I have cut. It is the least picky on ammo that I have ever seen.

The Krieger I have on a Gen1 Vudoo is awesome as well.

Did you order directly from Brux? Website says they have a 12mo lead time.

rimfired · Dec 26, 2024

Always have to have that 1 who wants to be a little different, 10 shot group at 100 yards today with Center X.

I bought them from Rachel Precision. He keeps lots of Brux barrels in stock and on order.

My RimX is headed to MCR for the ModX conversion. I was given the green light by Jonathan not long ago but I wanted to wait until after Christmas to send in the action. I was initially going to use an existing prefit but noticed Krieger had exactly what I wanted in stock ready to ship. Also thanks to Defender32 for the heads up on MCR’s new Eley specific chamber that looks very promising. Since Eley is super easy to get right now, that’s what I’m going with.
Good thing about all this is reverting back to stock config later on for whatever reason. I just need a new bolt head and slap on another barrel.
Edited to add: I’ll eventually pick up another RimX action and continue to run my Manzella barrel since it shoots so well.

rimfired · Dec 28, 2024

I haven't tried any yet but do have some left over Eley match I tried lot testing my previous rifle, asked about shooting Eley and he mentioned he uses a different Eley specific chamber if that's what you plan on shooting.

I got my latest Manzella Green Mountain to the range for the second time yesterday.

It was blowing 20-25mph and I was there to test my new Geiselle cut rifled ar barrel so didn't have a lot of time.

I shot a 5x5 with Eley Team then a 5x5 with CenterX and it hammered.

First 2 5rd groups of Team on clean cold bore was sub 0.5" then the next 3 were 0.2s..

First 5rd group CX was 0.4s then the rest were 0.1s and 0.2s.

Nasty blowing wind and this GM shot as good as the rest. No lot testing just grabbed some random half shot boxes in the cabinet..

Anyone shooting a Sidhe triggers from Italy?? Essentially an upgraded Flavio...

I just got 2 to test here. Their BR Evo and and Target Evo with flat 90 degree shoes..

I just threw the BR Evo in my single shot TL3 for some barrel testing and it feels AWESOME..

I'm going to throw this Target in my RimX to test but these Sidhe triggers feel great.

Question, after using the Bix&Andy, where I had to buy different sear heights for Vudoo and RimX, how would something like Sidhe just work? Compatible with both?

You didn't HAVE to buy different sear heights to "work." You bought different sear heights to be optimal for sear engagement.

If you look at the BNA chart. Both low and medium fell in the Zermatt measurement.

Also, from what I understand Zermatt made a change and low is no longer than optimal BNA sear height and it's now the medium sear (@Zermatt Arms) Ray please confirm..

Bolt cycling feels great with the Sidhe BR Evo, no premature firing.. trigger pull is crazy light and crisp around 1.5oz out of the box. I'll adjust it to around 4oz for my RimX.

I literally just mounted this trigger and dry fired it 50 or so times..

I have a lot more testing and some measurements to take so stay tuned. I'll start a new thread. Was just wondering if anyone was running one..

Having trouble using the site?
