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.
 
This would have been handy on Sunday
 
Hoping to get out on Sunday and do a deep dive into some ballistics. The nights are cool, so we should get a pretty good DA change from 7 till noon.
 
Thanks! That’s some good info and data points. If I get time, I’ll add that to my charts.
