RE: max point blank range
To start with what is the maximum distance that you want the bullet to be above or below the line of sight?What is the exact velocity of the load out of your rifle?What is the ballistic co-efficient of the bullet?What is the height of your crosshairs above the center of the bore?Once you have all the required data,you can estimate the maximum point blank range and the 100 yard point of impact.However remember that this is only an estimate and the actualpoint of impact may vary by several inches at 300 yards.
