Same tightness problem soaked in fine machine oil over night used hex wrench from Wheeler kit and a good cresent wrench to break it free. Replaced screw because socket was slightly damaged. Now torque to 45 inch lbs, and does not loosen while shooting.

I have a SigSauer Romeo3 (3moa) on my SW Victory it adds almost no noticable weight and is great for quick target acquisition great single plane focusing especially for older eyes.
