My rear sight on my James River 1903A3 looks new, but very time I shoot it aperture slides down. I have tightened small screw as much as I can. I'm shooting 150 grains at 2700 FPS.
Low recoil. Any thoughts on how I can fix this problem?

Try taking the tension spring off and bending the edges down slightly.
