19.25". Forgot to add that on this post.What is your barrel lenghth?
The difference between 2600fps and 2680 fps in the Hornady app is 600 vs 650 yards for dropping below 1800 fps at 800'. Probably more at hunting elevations, but both of those distances are already farther than I plan to shoot an animal anyways so no big deal. I'll definitely be better served by shooting more and practicing different positions, etc. vs gaining another 25 fps or something.
