I know the general rule of thumb is 25 for wood, 45 for laminate and 60-65 for synthetic. That being said, since it's plastic and not fiberglass or kevlar fiber I think I'll try 45 lbs per square inch. Anyone have any suggestions for this?
Didn't know the general rule on that, that's helpful. But you mean inch-pounds (torque), not psi (pressure).
I imagine it also depends not just on the stock material, but on whether the receiver metal is steel or soft Ruger aluminum.
I've read that for a 10/22 the action torque should be 20 inlbs, and the barrel block should be 20-25 inlbs. I've never played with the barrel block, but everytime I put the stock back on I use my torque screwdriver set at 20 inlbs. Then I will try to gently wriggle the action in the stock to see if it's oriented correctly, and try the 20 inlbs screwdriver again.
