How much elevation is necessary to get a 123 SST to 1000 yards?

[lrgrendel]

Assuming a 123 gr SST with a MV of 2550 fps, how much elevation is necessary for 1000 yards?

I have 42 MOA of elevation adjustment in the scope and a 20 MOA base, so this should give me 40 MOA total elevation adjustment, correct? Will this be enough for 1000 yards?

Plus all your info into JBM BALLISTICS and hit enter. It will give you a solution.
I shoot 123 AMAX at 1000 and do just OK at sea level. Of course your velocity is critical. I found my CHRONO said my amax's were going 2640 FPS when actually it was closer to 2600. For me JBM works really well and is bang on almost all of the time at the various distances.

Hope this helps.
