LabRadar

How do bullet companies calculate velocities past 100 yards? Do they have several chronos placed at different intervals, or is there a mathematical formula that can be used based on velocity at muzzle and 100 yards? Next question could you place a labradar at different ranges to obtain velocities past 100 yards? Ex: target is at 500 yards, place the lab radar at 400 yards to get velocity at 400 and then at 500.

Many if not all now use doppler radar.

Applied Ballistics has a mobile lab to give you a PDM, personal drag model for your rifle. If you use the same bullet lot, its incredibly accurate from all reports I have seen. https://appliedballisticsllc.com/mobile-lab/

Applied Ballistics also has their CDM custom drag models for bullets that is available in their library.

With the CDM from Applied Ballistics, that is gonna be pretty dang accurate at 400 or 500 yards with velocity. I've rarely ever had to tweak muzzle velocity to true it inside 600 yards with any bullet in AB using a CDM.

If you could trigger the labradar it might work, but getting it to trigger and track the bullet is gonna be interesting. It might also have trouble tracking a bullet that is dropping, I don't know anything about how "wide" the radar is, but I know if it is not aimed at the target well, it does not capture the bullet at all. There would be better ways to skin the cat than try that, IMO.

Thanks for the information! That answers my question.

LabRadar will only track a .308/.338 bullet for a distance of 100 yards at best per their literature. That is of course from the muzzle out to 100 yards
