I used worst-case velocities we've been seeing with the newer Hornady 123gr SST lots of ammo.
123gr ELD-M seems to be faster like the old 123gr AMAX load. Supersonic range has the corresponding wind drift with it. 123gr ELD-M isn't the best bullet for long range, but one of the most popular and available, so I used that.
I used .255 doppler-based G7 drag model for the longer range figures with 123gr ELD-M.
I used .462 G1 for the "within 500yds" figures on the 123gr SST for hunting.
All figures are with 100yd zero, 2.5" optic over bore height, standard atmospheric conditions (59° F, 29.53" hg barometric pressure).
Another graph to look at would be weapon weight with pictograph diagrams showing weapon length and profiles.
