Ruger use 1"x16v...........I think Winchester Mod 70 too.
I’ve built 2 tikkas and the 1-16” worked for them. Not older actionsI would be surprised if a Tikka didn't have metric threads.
I’m shocked the Rem required that much! I’ve trued up a bunch of newer ones and haven’t needed more than a couple thousandths to square the receiver face
Just measured a couple culprits. Model 70 and Tikka T3 threads are both 1-16 TPI, however tennon length on the model 70 barrels I could find averaged around 0.700", while the 5 T3 barrels were all dead nuts at 0.9855".
That's one thing I love about the T3 compared to some of the trash coming out of some of our factories now (looking at you Remington), the machining is fantastic, and you go to blueprint one and realize the it's already really, really good. I had to take almost 0.100" off a new factory 700 receiver to get it square, and the threads were way crooked, kind of like Freedom Group's upper management.
OP, if you didn't use a depth mic, or were rounding up, I'd say you may have a Tikka barrel. Up until about ten years ago, they were unmarked.
.... I had to take almost 0.100" off a new factory 700 receiver to get it square, and the threads were way crooked....
If it was that bad, why didn't you send it back?
I too have an unknown barrel tenon I'm trying to identify 1"-16 1.100 length, flat breech.
