[QUOTE="swampbug, post: 2620122, member: 115992"] A little context for the OP. In the scheme of ballistic calculations, of all of the inputs, the exact/precise scope height calculation is one that has the least impact. If you are within .125 - .25, you should be OK for short range. Just follow the mid bolt to mid scope measurement method. Understand, CDC's are neat and convenient on a standard hunting rifle. Know the distance and dial the scope. you'll be close. However, they are only as good as the ballistic and environmental information used to create them. Assuming you are not reloading, if you change ammo, the CDC is changes. Heck even if you buy the same ammo, the velocity may be different from box to box, so the CDV changes. The zero at 100 must be right. Also, if the environmentals change, change in altitude, temperature, etc. , the CDC changes. Not trying to beat up CDC's. Just trying to point out how an exact scope height has little to no impact compared to other inputs. [/QUOTE]
