Does anyone know the torque specs for the type 99 action?
Type 99's have an index mark and you need to align the barrel index mark with the receiver index mark. Once aligned you will need to head space the bolt.
I appreciate your response but I’m asking about the torque spec for the action screws through the trigger guard not the barrel to receiver.Quote:

Tighten the forward screw first . Mark 1 - Please tell me how you change the headspace on the rifle after the barrel is installed to the index mark ?
There likely is still evidence of the staking on the action screws and you should be able to line those up to get what it originally would have went into service with.Quote:

With about 80 years of stock shrinkage the old marks will not matter any more . If you do not get them tight you can crack a stock with recoil . Just look at all the tang cracked Mausers out there due to people trying to use the locking screws , incorrectly .
Thanks to you all for the advice given. I’ll use the advice and apply it to my rifles.
You need to CHECK the head space every time you change the barrel or bolt.
If the barrel does not head space you may need to chamber ream barrel to achieve the correct head spacing. Or try different bolts.
I asked how you headspace the bolt AFTER the barrel is installed , like you said .
