What I do is run the screws down barely snug, then tighten the recoil lug screw down tight. I would recommend experimenting with the torque a bit to see how it affects the groups. Since all rifles are different, the amount of torque will be slightly different for optimum groups. The wheeler fat wrench is reasonably priced and will measure exact inch pounds.
..........stalkingbear gives good advice. The Wheeler Fat Wrench is a good tool to have. It measures inINCH pounds which is what you wish to torque to, and has a chart with it for recommended torque for various actions. The Rem. 700 is listed. The wrench is not that expensive, and comes with various sized bits to fit the action screws perfectly. If you are going to do any stock work at all, or just want to be able to check the screws for proper torque, it's hard to beat.
