I saw Bryan Litz of Applied Ballistics on a Utube discussing Aerodynamic Jump. He said the Applied Ballistics software accounts for it. He made the video 6 years ago and at that time no other software did account for Aerodynamic Jump. Today the Hornady 4 DOF software also accounts for it. According to Hornady , 4DOF doesn’t even use the ballistics coefficients they publish, in 4 DOF. The 4 degrees of freedom are elevation, windage, range and “angle of attack” (new 4th degree). 4 DOF uses a drag (coefficient) curve itself citing that use of the ballistics coefficient is mathematically inferior to use of the drag curve because the ballistic coefficient changes as the velocity changes and the drag curve doesn’t. I imagine since most people never used it or had the tools before to use Aerodynamic Jump, the variability in shooting results was attributed to errors; wind, bad hold, less than ideal trigger release, etc. The impact of Aerodynamic Jump out to 400 yards for my 6.5 Creedmoor seems to be about 0.3 MOA either low or high depending on if wind is blowing from left or right. 0.3 MOA at 400 yards is about 1.2”. As long as the group is good most people would probably accept 1” high or low at 400 yards without thinking about it as it’s only 1 click on the turret. For me , my shooting form and trigger technique dominate my shooting results, once I have worked up a good consistent load for my rifle. It’s really neat to learn about all these hi tech tools. And I can imagine for long range work in the 700-1600 yard range this parameter being more significant.
