[QUOTE="misterc01, post: 1641442, member: 109160"] Screws- Yu said tight. Are they tight by hand or torqued? Minute variations in pressure can do strange things. I learned this with a Ruger 10/22 - Under or over tightening the screw caused POI shifts. So I used a torque wrench using inch-pounds and torqued until my shots grouped the best. I believe Ruger says 110 inch pounds, but other forums have used up to 30 inch-pounds. On my longer range rifles, I use the factory setting to start, and try a +/- variation test. Just another thought on variables. [/QUOTE]
