do you blue print them ?
do you seat barrel face against both inner and outer ring ?
i used an f.n. commercial with sako trigger for years ... sold it to a returning vet ..made me feel good ... well mostly.
keep up the energy !!

I don't blueprint Mausers unless you consider cleaning the face of the action and the inner ring to be doing that. I have found no practical advantage to cleaning the threads up as threads are a lousy way to align anything anyway, and if you get differential hardness in the front ring (which happens occasionally due to the case hardening process) you may be doing more harm than good and feeling great about it.
On this rifle, I seated to both rings at crush, but often I will hold off the inner ring .010 so that the outer ring carries the burden of alignment/harmonic transference, but that's only if the action is off at the inner ring. Suffice it to say that I make sure the action runs concentric to the barrel via fixturing I have designed. I try both shoulders one at a time on the barrel as it is mounted in the lathe just after threading. If they are both satisfactory and produce an action TIR of less than .010 10” to the rear of the threads, then I will seat to both of them. If not, then I clean the face of the action as it is mounted on the barrel and then check it for alignment. When it is aligned, it is used.
My build philosophy is different than some because I designed it myself (like I do everything else). Many smiths build by blanketing reasonable precision over the entire rifle. I put extreme precision where it can do the most good and let the rough edge drag in places that sound good, but lend no practical advantage to accuracy.
At the end of the day though, “garbage in” still equals “garbage out". Like my dad always told me “you know son, you can cut it and cut it and its still too short".LOL!
