Range Report Kestrel 4500 AB input

[300 jarret]

Is it better to use the MV aquired from my chrno(magnetospeed) or the MV calculated by the zero/ drop program of the the Kestrel ? I have 2 chronos , a Magnetospeed and a Chrony Gamma Master, It seems the magnetospeed is more reliable. JVON

Your first step is to chronograph your rifle/ammo combo then input that reading into your gun profile (MV) along with the other input variables. Be sure that your inputs are accurate ex. SH, BC, ZR... If your ballistic Firing solution isn't matching up with your actual drop (what your physically seeing downrange) then you want to conduct a calibration on the variable with the greater uncertainty and through the supersonic realm of flight that variable in muzzle velocity. Under GUN, scroll down to Cal MV and hit center button. On the MV Cal screen you will see a range in the top right corner, that is the recommended range to conduct a MV true. Simply set up a target within that range +/- 50 meters/yards and record the actual drop needed to hit that target. Be sure that the calibration target range is confirmed with an LRF and take caution on measuring the drop, any error will lead to an improper calibration. Once drop is set simply hit the Cal and then hit back button to accept mv Cal. The new MV will be used.
