[QUOTE="Buffalobob, post: 119575, member: 8"] A few instructions as best I know. These two programs are "examples of how to do it" They cannot be used "as is" They are set up for for a particualr gun shooting a particular bullet of a particular BC at a particular speed, altitude, etc. What you need to so is Using a ballistic program compute a drop chart in "inches" for YOUR particular gun, etc. Most scopes are marked in quarter inches but the circumference of the scope knob and how many inches a turn varies. I believe my two Luepolds V3 have 15 inches per turn. So your little tiny strip of paper must have that many inch marks for a complete wrap. Getting the program to print the right size so you get 15 inches spread correctly on the sheet of paper is a trial and error exercise. In all of of this you have to go in and put your 200yd , 300yd, 400yd etc marks. These must have been field verified or once you have the paper wrapped you can actually use a waterproof pen to mark on the paper as you shoot the gun in. You then cover that with water proof transparent tape. I did not ever personally use either one of these two programs. I acquired them out of curiosity as to how the computer programs were put together. [/QUOTE]
