[QUOTE="Buster Hemlock, post: 2057845, member: 109327"] So I revised my previous post. That was with a 5 mph left to right wind and also spin drift. So what happens if we get rid of the 5 mph wind and spin drift too? Cant Drop Wind -2* -65.18" -3.09" 0* -65.23" 0" +2 -65.18" 3.09" Took it out an extra decimal to show that the 2 degrees left or right is causing minimal effects on your elevation but that .05" does go somewhere and it's creating 3" left or right at 600 yards. It's a trigonometry problem that thankfully apps/kestrels do really fast for us. Now think if you zero your gun off 2* at 100 and then line up for a shot and are -2* at 600. No wind, no spin drift, no aerodynamic jump.... oh my! If you really want to get into the weeds and understand all this stuff I'd recommend Bryan Litz's books available through Applied Ballistics.
