1. How much torque should be put on the screws mounting the... The side bolts/screws have a large range of torque specs depending on what rings you have. Tactical rings that attach with a socket can handle as much 65 in/lbs, I'd probably say about 25 in/lbs on standard Weaver-style bases.
I don't know that anyone lists a "correct" torque spec. I know many guys who torque their action screws to somewhere between 40-50 In/lbs. Please do not torque them in Ft/lbs, as you will snap them off, or strip them out. I torque mine to 45 In./lbs. Maybe some of the other gun companies list specs, but I've never found any for my rifles.
