Mil laser rangefinder
If you rely on the readout for holdover from a rangefinder you are relying on data from an internal ballistics program.
If you are using a ballistics program, even a crude one, first make sure that you have correctly entered, at minimum, BC, temp and station pressure, and muzzle velocity.
You can't do any of that with any Bushnell. The Bushnell, even the new one, uses ammo 'profiles' designed for hunters shooting large targets at relatively short ranges.
