How To Zero Another Load At Your Current Zero Range
Most hunters and target shooters eventually want to try out a new load, yet they often want it to zero at the same range their current load zeros at. To accomplish this, you need to know how far and in what direction to turn the scope's elevation knob.
Find your gun's current sight adjustment for the load you are using and the range you are zeroed at. Change the Muzzle Vel and BC parameters to those of the new load. To calculate, click the Options button and then click Calc Trace Values. The sight adjustment value is now the setting needed to zero the new load at the same range the old load was zeroed at.
Use the two sight adjustment values to determine how far and in what direction to turn your scope's elevation knob. This is covered in How To Change a Gun's Sight Adjustment.
