Figures are the maker's published BC and muzzle velocity in the maker's test barrel, solved with ZeroDope's point-mass engine at 59 °F, 29.92 inHg, sea level, 100 yd zero, 1.8″ sight height, 10 mph full-value wind. Your barrel, your chronograph and your conditions change them — the app corrects for all three, then you true it on steel. Terminal figures are energy floors from the sources on each animal, not a licence; legal minimums vary by state. © ZeroDope.
