[QUOTE="LouBoyd, post: 568211, member: 9253"] Once you need "a few clicks of compensation" then you need a either a range card which matches your ammo and environmental conditions or a ballistic computer so you know how many clicks "a few" is and in what direction. At that point you might as well use target knobs calbrated in MILS or MOA and just look up the numbers on the cards or computer. The lookup cards or ballistic computer can correctly compensate for any parameter you can measure. It's the parameters you can't correctly measure which will remain the major source of shooting error. Usually the largest error is from downrange crosswind deflection. Getting exactly the same powder burn other than to achieve the same muzzle velocity is splitting hairs compared to the atmospheric variablility from shot to shot and day to day. [/QUOTE]
