I have been struggling to get an accurate DOPE card. I have found that SK Pistol Match Special and Eley Team shoot amazing (sub moa) out to 250 in calm winds. I have shot at 100 yards using my 50-yard zero to try and true my velocity. I found it drops 18 1/2 cm or 7.28 inches on average. I am unsure of what ballistic coefficient to use in my calculator. I have looked around and found people using .110 to .175 for their BC. I do not have access to a chronograph right now, although I have considered getting one. I have used multiple calculators to get consistently inconsist resuls: GeoBalistics, Hornady, Balistics AE.
