Gentlemen: Again we have left out the obvious. Brownells.
Brownells has been listing an adjustable T handle torque screwdriver for the last few years that would seem to have all that is needed for gun work. It has a range of settings that is just right for both scope mounting, and action tightening repeatability. Most of those that you have listed would do for rings and bases, but not for action screws. I've seen action screws torques quoted to be around 60 inch pounds. I've kept looking at low value torque wrenches, and think that my 3/8 drive Craftsman with a 1/4 inch socket and the correct screwdriver bit in is all that I need.
Does anyone have a Brownell's T Handle that we can have checked?
I don't think I'd bother to spend my money on a cheap Wheeler. Too much like buying a used barrel, and having someone else rethread and chamber it.
