I was about to start a post on this subject. I was at the range yesterday. attempting to zero a new scope on a .223 AR 15 rifle. I set my target up at 25 yards and had a nice tiny group. I then moved the target to 100 yards and could not get a bullet on the paper. I finally had to line up the rifle scope on target and then fire a round looking over the top of the scope to see point of impact. I figured that I should have been about 5.5 inches high but that was a bit off.
My scope is 2.5 inches from the barrel at the center of the aperture lens. Target is printed on an 8.5X11 sheet of paper. Yes I know I should have brought a larger target but I didn't think I could not at least be on the paper at that range. I was overshooting the target.
What I am looking for a simple calculator that will allow me to input the scope height along with the zero distance and then calculate point of impact at a given range. Must be Android compatible. I don't need to learn how to build the watch, I only want to know what time it is. These applications do not come with a good explanation of how they work and I can't seem to find one that I operate.
