NEW From Zermatt Arms - RimX Actions

[021411]

Did you get the eley chamber? I’m waiting on Randy Rachel to build a modx for me.

Indeed. Modacam doesn’t have a specific name for the chamber but its chamber “E”.

My 13t with Jelrod Eley chamber is headed back to me this week or next. Johnathan knows I'm in no hurry for it.

The Brux barrel Randy Rachel spun for me LOVES Eley and Lapua ammo. I have had ZERO issues with it. @Csafisher you will be happy.

@021411, How long did Jonathan Have it? He has mine right now, and I am eagerly awaiting its return. IIRC he has had for two months now. Could be off by a few days.

Great! I’m getting closer. Thanks @021411

 

[Jeffd]

Very happy with one. Very smooth.

Same Here!

is there a serial number that the problem was stopped by? I just got my action I don’t want to start the galling in hopes it’s ok. Is the root cause hardness of the bolt or bad material?

Those more privy than myself, please correct me.
There are reports that a material change occurred somewhere around S/N 3000.
Zermatt has said a geometry change addresses the issue. Does that mean the material change will stay? Why would a material change necessitate altered geometry? I haven’t followed as closely as I would like.
Some have gotten new bolts; among that group, some had no issues, while others still experienced galling.
Who knows?
I placed an order a couple weeks ago and was quoted 18 weeks. That’s fine with me. Quality over expediency.

Per Ray, "..we've changed the geometry on the leading edge of the affected area to drastically increase the amount of surface area that will interact with the receiver at the initial contact point." Increasing surface area in contact during the high stress bolt close distributes the force over more material, reducing the wear on the bolt during operation. It sounds like the material & state originally used for the bolt did not have issues with the peak forces experienced, but the new bolt had issues with gouging when experiencing the same forces during operation. There are lots of reasons to change materials, from cost of production to raw material sourcing, so if changing the geometry of the bolt fixes the gouging issue, that's a better change than going back to the other material for Zermatt.

 

[Csafisher]

It doesn’t appear to have completely fixed it. Some are still having issues.

I replaced 5 of them and all is good with all 5.

The whole thing was handled very poorly by the manufacturer. The cover up is always worse than the crime.
