Gunsmithing SAKO TRG-42 barrel diameter

[gol1]

Hello

I am looking for the maximal barrel diameter and length in the breech area of a Sako TRG-42 338LM factory contour barrel, my rifle is installed in a Cadex chassis so its not accessible
really appreciate any help.
Thank you!

Looks kinda like a medium Palma with less breech meat.

I’ve had that drawing for like 8 years haha. I don’t even remember why I did it. Probably thinking about rebarreling my original -42 and wanted to compare it to available contours.

I know this is an old thread… Does anybody know if the 300 win mag version has the same diameter at the breach?
