CZ 22 chambers...Std or Match ?

I've looked at 'standard chambered ammo' and haven't seen any marks. Maybe just 'rich-bitxh' "air-kisses" :rolleyes:
'per google, Copy paper runs ca 0.003 to 0.005" - I can see paper sideways.

If you shave 0.015" off the breech face of a standard chamber CZ barrel, you get about 0.020" of engagement of the bullet into the rifling. The standard chambers must be cut to just "kiss" the bullet, 0.005" of engagement isn't something you're going to see or feel.

So theoretically, you would have to shim the bolt out by 15 thou also. That is a silly way to do it.

Why would I shim the bolt when I can just set back the barrel shoulder the same amount in the same setup as the breech facing operation? If you guys want to learn something, just ask.

In my defense, I did ask for clarity, and you had not previously mentioned setting back the face for the barrel tenon.

While shimming the bolt would work, this is the proper way to do it.

To be fair, Rabid (or Leuchtkafer) did say the following in post #40. It refers to taking something off the breech face.

I got that , it was the bit about facing the shoulder of the tenon that was missed. Just facing the breech would increase distance between bolt face and breech face; barrel would need to be set back in order to tighten up head space.

This is what I did not understand.
