LOL, Guess I may just have to do myself a favour!
I am telling you, you do not need one...….
I am still on the fence, but....... thinking about a Interarms Mark X 30-06 re-bored to 338-06 be JES. Hmmmmmm!!!!!!!! Already looking at one.
With the taper on the ‘06 case, it really is easiest to go with a CRF Mauser action and a simple rebore.
If you haven’t seen it, search out AlaskaLanche’s thread on his 84L bored out to 338,
and lopped off at 20”. — Lite Done Rite , iirc was the thread title
