Gunsmithing 338 Winny rechamber to Norma

[MWDG3]

Anybody have case dimensions for the 338 Norma? Specifically head to shoulder height. I can't get anything outta Norma yet. Also have both PTG prints but can't tell which dimensions to compare for sure.

I want to rechamber and was told the Winmag shoulder is a little taller and requires and unsafe amount of thread tenon to be removed.

I took some measurements from my reamer and go gauge. From the case head to the body shoulder junction I get 1.8750" the dia at the shoulder body jucntion is .5760". Please note I did not bust out the comparator for this but youll be in the ballpark with these measurements.

Thank you sir. Looks like 1/8", too long for my taste. Guess I'll forget the 300's.
