Re: how much to torque action screws?
For more detailed info, check my post in the Getting started section on a 300RUM.
If your rifle is properly bedded, you only need firm hand pressure on the action screws. The screws will go from loose to full tight in 1/2 turn. No mushiness, or increasing tension/creep.
Situations where heavy torque, mushiness, or increasing tension/creep is apparent is a clear indicator that the bedding is out of whack.
Most commomly seen in expensive synthetic stocks with CNC alum bedding. These have some of the worse bedding made today. I go into lots of detail in my post.
