My rifle is identical to yours, except trigger. Same scope.

My average velocity with that ammo at similar temp/barometer/humidity is 1085fps. Elevation ~165 feet ASL, range heading similar to yours (almost due north).

DOPE is within 1/4 MOA out to about 150 yards. At 200 yards, I observe about 1.25 MOA less elevation required than your value (22.5 vs 23.75).

Some of this might be attributed to velocity difference... but the aggravation is in finding a BC that works from 100 to 400 yards. I need a higher BC to work past 150 - at "normal" rimfire BCs of .130 - .150, Strelok Pro gives me almost identical elevations to yours, and they are too high 200-300.

Rimfire. Voodoo. Animal parts/sacrifices, not the awesome rifle maker.
 
Had to convert it.

Makes sense. Probably a good starting point for most people.

Height over bore is about the only variable I don't see listed.
 
My scope sets 1.44 above bore. For my distance I used my Leica range finder and set a 100 yd plate then used a tape and set the other plates at 10 yd intervals. My tape is only good for 50 yards. My 50 to 100 yards was all taped.
