I am having a hard time convincing an individual that in order to use a ballistics calculation,you must know the sight height.He insists that if you know where the point of impact is at 50 yards,you can use the calculation to find the point of impact at another rangewithout knowing the sight height.He claims that different heights of rings will not effect the results.Your opinions on this?
My opinion is to send the young boy to a good geometry class. And buy his books and teach him something.I can't believe all the folks who take these calculators so serious without trying them out. I have seen shooting past 500 yards where .1" makes a world of difference.
I use sight height as like "k" value. Math guys know what I am saying. Bascially use the calculator to get you on the paper at 500 yards and then take your velocity, BC, and altitude, and spit that into your bullistic calcutor and play around with sight height until you match up your real time results with the calulator.
