Gunsmithing Tikka Barrel threads-metric?

[hill billy]

Trying to set up to get one re barreled and I don't know if these are metric or not. I would assume so being from Finland. Any ideas?

The threads for the brakes are so I would assume it is metric on the other end too.

we just pulled a barrel on a Tikka 595 to build a switch barrel and it had 1" X 16 threads on the chamber end.

My Tikka T3 is M18x1RH.

The 18x1 mm is the brake threads. Skeetlee, i have had two done by Brian Wick in Albion,il. One was a tac with the metric brake threads but the action/barrel threads are 1" 16 tpi. That was his first tikka build and he assumed, like me, that it would be metric since the brake was. The second one was also 1" 16tpi. Either way he wasn't too worried about threading metric, he turned a 1/2x28 ops inc brake to 18x1 mm so it would screw on the factory metric brake threads.

I should clarify, he did the brake rethread 1 yr before the rebarrel. He also trued the receiver face back to the flats, that way i could run a 1.2" lv contour. If that taper is left on there the biggest u can run is 1.10. The first action was dead nuts on with minimal lug lapping needed to get full contact. The second one had a little more contact on one lug than the other

And to add (yet another) wrinkle to the topic, the CTR's are stated to be shipping with a 5/8-24 muzzle thread...

Maybe those have metric action threads,lol.
