The Exbal ballistics calculator has a reticle analysis function. It produced the data below for the Vortex drop-dead bdc reticle. The "holdover" values are per Vortex for each dot below the crosshair. I have not tested these numbers yet. I did use this method on a Leupold VX-3 with a varmint hunters reticle and at 400 yards the POI was within 1/2 MOA of the POA. FWIW
