[QUOTE="shortpants, post: 719877, member: 30564"] It took me a long time to learn to get a calculator to match my drops but I've finally done it. First piece of advice is only test on great condition days. If conditions are questionable then your results will be too. It is absolutely crucial that you are 100% confident in your zero wether it be 100, 200 or whatever. If you are testing drops always start with verifying your zero. Beyond 400 yards angle becomes an issue. In my experience I don't see a lot of shots beyond 400 that are more than 25*. When I have seen angles like that it is a very steep canyon or mountain side. Most people over exaggerate angles. If you are indeed testing at extreme or even moderate angles you need to find some way to try and figure in the angle. A guess might be better than no consideration but I advise you find a way to measure the angle. Like Jeff said shoot at various yardages (400,600,800,1000) for example. Does not have to be exact as long as distances are known to be accurate. An error in range can make you scratch your head. Shoot good groups! Adjust velocity until your calculator matches your real world drops within .25moa.
