For my Walnut stock TX200 .22 HC in FAC power:
Scope ring screws: 15 in-lbs
Scope ring dovetail screws: 35 in-lbs
Front stock screws: 12 in-lbs
Rear trigger guard: 20 in-lbs
and last but definitely NOT least the Front trigger guard screw: I have tried 8 in-lbs, 10 in-lbs, 12 in-lbs, each of which has failed miserably to maintain accuracy and also loosens off within a few shots. I finally reached 15 in-lbs and the rifle finally started to shoot very accurately. BUT, even at 15 in-lbs, it comes loose after about 15 shots and has to be re-tightened. So, I have ordered another Felo torque screwdriver head so that I can try some values from between 15 to 18 in-lbs. I have also ordered an OEM 12 fpe spring to try out. I can't stand a rifle that won't shoot extremely accurately and consistently. I will eventually figure out what the .22 HC likes.
I also have a TX200 MKIII beech stock in .177 with a 12 fpe Vortek kit and it is a laser, with consistent 0.5 inch or smaller 10 shot groups at 50 yards in calm conditions with 10.3gr JSB Exact pellets at ~725fps. The front trigger guard screw is torqued to 12 in-lbs on it and it is holding perfectly. The rest of the screws are torqued to the same values as the .22 HC. It is an absolute joy to shoot.
Bottom line, like pellets, torque values which may work on one rifle, may not work on another, and the torque values which work may require accuracy as well. I don't want to damage the stock by overtightening.
