are shouldered barrels for these two actions interchangeable? That is are the distance between the bolt face and lug the same?
 
I do not believe so. The TL3/Origin are different and both made by bighorn, can imagine actions from two different vendors bei g same thread & headspace. I'd get a tennon blue print from both vendors and check the measurements.
 
I'm not sure what the dimension is on the Bighorn action, but on the Nucleus/Mausingfield/Archimedes actions the distance from the barrel shoulder to the bolt face is .825".

They would have to be EXACTLY the same which is why I use barrel nuts on my Remington 700's, Mausingfield, Savage 110s and Ruger American. Also I make the barrel breech face flush with the chamber on the Remingtons just as on the others: SIMPLIFY!!!
 
Nucleus/Mausingfield/Archimedes actions, barrel shoulder to bolt face is .825 +/-.002
Barrel tenon is referenced at .673

Origin action, barrel shoulder to bolt face is 1.025
Barrel tenon length is .890 +.000/-.010

TL3/SR3 actions, barrel shoulder to bolt face is .925
Barrel tenon length is .790 +.000/-.010

According to the prints I have, all actions above share the same 1-1/16 - 20 TPI thread
