I didn't know Zermatt actions have a thread relief cut at the receiver ring...@Judd
You can see the Auto retract threader in action on this barrel I did yesterday, it starts at 10:32
Still need to thread the muzzle for 5/8-24 I may video that as well.
We're waiting on the stock for this custom build, that's going to be quite a ways out yet unfortunately.
Apologies for the audio - I did the best I could. I'm just a guy in his shop doing what he likes, I'm not a professional Videographer.

Zermatt TL3 - 25 Creedmoor Thread, Fit & Chamber
Thread to fit is fine, but for a precision action it would be much faster to just check your PD with a thread mike when you get close- then you'll know exactly how much deeper you need to go to hit the required PD number, particularly for class 3 fit. Once you've got the numbers for any given action/bolt, you can cut replacement or different cal barrels for a customer without needing the receiver in hand.
