Saands,
There are so many variables. If you don't have it yet, get a copy of "The Mauser Bolt Actions" By Jerry Kuhnhausen. You can get it from Brownells (
www.brownells.com) or Midway USA (
www.midwayusa.com)
This book is the bible of Mauser rifle gunsmithing and has much useful info.
Myself, I stay away from actions made during the second world war, and test by using a scribe on the bottom of the action. If the action is hard enough, the scribe will not mark a line in the action. Not very scientific, and it still does not tell you if the action is too hard. I send out any action that is to be used with a high pressure cartridge to be tested and hardned if necessary. Standard pressure (30/06) type cartridges just get the scratch test. Read Kuhnhausen's book and decide for yourself.
Happy New Year-John K
