@Beiruty ok at this point we all know your argument is flawed. No amount of data and experience to the contrary is going to change your mind.
Ballistic calculators use a static BC and Velocity to come up with a solution. This is only valid for that exact BC and speed. Unfortunately BC is different from bullet to bullet and lot to lot. May not be much but it’s enough to induce very minute error.
As we have shown velocity also changes with unknown variables. Again, the calculators are very good very close approximations.
Applied Ballistics runs around to PRS matches and ELR matches using their high dollar setup (including an advanced dopler radar) to give custom profiles (for their Kestrel Elites) for a shooter’s lot of bullets, powder, primers. It is only good for those items and that gun. Change 1 thing and the results may not be as good.
At the end of the day, you are wrong. WRONG. Your wiz bang hypothesis is flawed.
The fact that you referenced 4DOF is laughable btw. Anyone who relies on Hornady is suspect.
Good day.
