Tested FX 81 gr 357 pellets using a Labradar and the Pyramyd air calculator I’m getting BCs between 0.036 and 0.040 ( 50 degrees out, 1400 feet elevation, average muzzle velocity 847 fps (out of my Impact 0.35) according to Labradar, 855 according to FX chronograph.)
Anyone know of a way to enter all the data (speeds at various distances that Labradar provides, averages over a whole shot string) rather than entering the speed at two distances for all combinations? Seems like 0.036 to 0.040 is a pretty big range of uncertainty and averaging a bigger data set might reduce the uncertainty.
