Download and save this Excel armboard data card. Perfect for competition shooters, snipers, or designated marksmen. It is sized to fit in an Under Armor QB sleeve. You can fill it out on your computer and print it out, print a bunch on card stock and fill out as needed based off current conditions, or print it out blank, laminate it, then write on it with an alcohol marker. For typical urban overwatch stuff, if I don’t have specific target reference points, I’ll just do 200-600 yards in 50 yard increments. You can easily interpolate anything between the 50y brackets by adding .1 mil for every 10 yards.
