The round leaves the bore 3 inches below the line of sight. Just a quick calculation with a 62grain 223 round with the center of my scope( line of sight) 3 inches above the bore. When my line of sight by-sects the arc of the bullet where my line of sight is 3 inches above the bore my bullet has to rise 3 inches to cross my line of sight, it then has to fall 3 inch to cross it again. Lets say we are shooting a round that when sighted in, does not rise more then 6 inches thru it arc. The trajectory of the bullet should be an arc not a desending line. The line of sight should be flat not angled down, and the bore should angled up not be flat. It shows the bullet never rising above the line of sight, yet you know that it does. The picture with the deer is correct, but Mike that line graph is not correct. To learn how to do it on the cheap, use a 22LR and keep your maximum range less the 100 yards. The chart is what should happen, you then make adjustments for the real world. ![]() Yes you will have to do a bit of shooting and will be shooting two targets at two ranges by the time your done. Then after you have a chart on paper, you go to the range and start shooting for real. The bullet must always travel in an arc, your simply trying to keep the arc with in a couple inches of your line of sight. ![]() You also can adjust the height your line of sight is above the bore( scope reticle) to change how far the bullet has to rise to cross the line of sight. You will see on the chart were the bullet crosses the line of sight both on it's way up to the top of it's trajectory, and where it crosses a second time on the way down. Find and then adjust the range that your bullet rises across your line of sight by setting the rifle zero to various ranges. Does anyone know if zeroing at 100 yards gives you a similar trajectory, or know the math to figure this out?Use a ballistic calculator. This method, basically means you could shoot down a 5" pipe and not hit the walls.
