[QUOTE="WildRose, post: 1798810, member: 30902"] Unless you're setting them up wrong or plugging figures into your programs errantly my guess is that the problem is in your reloads. If you don't have your ES and SD down into low double or even single digit range it's going to be difficult to come up with accurate calculations for your dope beyond about 600yds with most rounds. You also have an issue that BC's are not static and may vary from load to load, rifle to rifle so you need to verify your drops at longer ranges (I like 300, 500, 700yds) and then tweak your BC in your programs to get your predicted data to match your real world measurements.
