[QUOTE="Bravo 4, post: 2421971, member: 8873"] Divide obj lens diameter by 2, multiply that by the difference in range between where your parallax is set and the target, divide by the range your parallax is set to, this will give you a solution in mm and to convert to inches multiply by .03937 (or however you want to round that number). example: 50mm scope obj parallax set @ 100 yards target @ 900 yards difference in yards of parallax setting to target of 800 yards 50/2= 25 25x800= 20000 20000/100= 200mm 200mm x .03937= basically 8" max PA or make you a chart with [URL]https://www.lelandwest.com/parallax-error-calculator.cfm[/URL] added: will I take this as gospel...No...but can give you an idea.
