How To Find a Gun's Sight Adjustment
The first step in putting the program to practical use is to find out what the sight adjustment of your gun is. Once you know the current setting, you know what direction and how far you must go to change to any other setting.
Even though you are dealing with very small angles, finding the current setting is quite easy. If you haven't already done so, the first step is to zero your gun in at some convenient yardage using your favorite load. You need to know the muzzle velocity of the load you are using and the ballistic coefficient of the load's bullet.
Once you have this information, open a trace window, set the Find parameter to Sight Adj, and enter the ballistic coefficient, muzzle velocity, and zeroed range. Click the Trace window's Options button and then click Calc Trace Values. When the program is done calculating, the Sight Adj parameter will hold the current sight setting of your gun. Record this setting so you can refer to it later.
