Welcome to the Forum.
I wish I could help you, but I don't recall seeing it listed anywhere. However, I have used 30 in.pounds before as I was thinking of the amount used on scope bases.
The take-down screw should be tightened to approx. 24 inch-pounds.
On many 10/22's, it will have an effect on accuracy. You might want to adjust it up (a little) or down and try it.
