Headspace shims?

[CZ550]

Has anyone ever heard or used some kind of shim to set headspace ?

I had a 22-250ai I rebarreled, but decided I want to use it again this summer on PDog hunt. When I had the rifle rebarreled I had action trued up thinking I wasn't gonna use the barrel again.

Thanks Corey

I have used a "shim/spacer" to set head space. It's almost like the recoil lug on a Rem 700 sandwitched between the action and the barrel.

Where did u get them ?

I am interested in how shimming the head-space would work? Do you extend the head-space by adding between the receiver and recoil lug and barrel? Can you reduce headspace by adding a shim to the bolt face or would you remove material from the recoil lug or shoulder of the barrel?

It would be hard to shim the bolt face and have the extractor still work as planned.
No problem surface grinding the recoil lug to adjust the headspace, or trimming the shoulder back to do the same thing..

I made the "spacers" on my lathe, as the barrel had the same thread but a longer tennon, it came off of another action. Was the action thread re-cut when your action was "trued"? If so the thread would be too sloppy/loose so you not only have to set the headspace but you would have an oversized thread in the action. If the headspace is "too long" you would turn the shoulder back to adjust.

When you're dealing with any headspace issue, I'd do it right or not all! Shims have no place there.

The face was trued no thread cutting.

You should tell Kelbly that. I can get a shim for my grizzly.
