For those interested, the LabRadar chronograph allows one to compute BC for their projectiles. The instrument operates by means of radar and will measure velocities at 5 distances up to 100 yards for 40 cal. bullets. Using the velocity at the muzzle and the velocity at the100 yard mark and JBM's BC calculator one can arrive at a BC for the bullet. Yesterday, based on 10 velocity measurements, the BC for the Paul Jones creedmoor bullet was calculated to be .358 which I think is a reasonable figure given the bullet shape.
