F Class buddy sent this along with the note: "Found the high node"

The "V0" velocity is not actually measured, it is calculated. The Labradar doesn't start tracking the bullet until is is approximately 10-15 yards downrange, and it measures the constantly from that point until it no longer sees the bullet (distance) or the bullet hits the berm. It extrapolates the V0 (muzzle velocity) based on all the measurements to determine how the bullet loses velocity over distance.

The Labradar creates a file that shows the actual velocities measured as the bullet is going downrange. It puts it in a subdirectory labeled "TRK". It would be interesting to see that data.
 
Is V25 and V50 the measured velocities at those distances? I can’t imagine the ballistic coefficient of a bullet that looses 900fps in 25yds, maybe the unit picked up something other than his bullet.

That would be my guess.
 
It might be that there were more than one Labradar at the range. There is a setting for the radar's operating frequency, could be that there were two on the same frequency and they interfered with one another.
