Gunsmithing 1-1/16 - 20 TPI 3A Thread spec sheet

[AZHUNTER]

Anyone have a thread spec sheet for 1-1/16 - 20 TPI 3A threads, I will be attempting to thread/chamber a shouldered barrel for my Bighorn Arms Origin. The origin is advertised as using savage small shank threads and from what I have found the barrel tenon is usually turned to 1.055+ on prefits, I would like to see an actual thread spec sheet if one exists, but i will still just measure the action once it arrives hopefully in a few weeks or less and go from there.
Thank you

I can't guarantee the accuracy of this calculator, but every one I have double checked with the Machinist Handbook has been dead on. http://theoreticalmachinist.com/Threads_UnifiedImperial.aspx

A 1.055" major is still in spec for a 1.0625-20 3A.

Helpful link thank you. l had thought if tenon turned to major diameter of 1.0625 it would be unlikely to fit the action, looks like its going to be best to measure it vs going minimum spec. I appreciate you posting the thread calc link.

Theoretical Machinist was my goto for a while, but I discovered this one and like it because it has metric too:
