Hornady A-Max

[7mm STW]

Have a 243 shooting hornady A-max 105 grain at 2950 fps. I have shot the gun at distances to 800 yards including 700, 600. I have not been able to get info on JBM or Bergers to match all three moa. So when I get 700 yards on the calculators to hit what I have shot It is high on 600 and 800 up to 2 moa. Any thoughts or do I need to shot at all ranges and build my own drop chart. 14.5 moa at 700. 20 moa at 800. 6 moa at 500 yards.

My first thoughts are your scope it not tracking 100% or your inputing some of the data wrong.

Lets here a bit more about your scope

I agree with the above, alot of scopes aren't what the manufactures say or incorrect input data

This might help sighting in elevation 6000 feet and 65 degrees.

Been dealing with this myself with my ultramag and it turned out to be a simple fix. My "0" somehow ended up .75 high @ 100. I rezeroed and all data fell into place.
