The Muzzle Velocity Calibration function allows you to 
obtain a more accurate muzzle velocity by combining 
user input data and actual shot results and calculating the 
actual bullet speed.   
CALIBRATING MUZZLE VELOCITY:

 

» Scroll to and select Gun in the Ballistics Menu.

 

» After accurately inputting all other gun, bullet, and 

scope parameters, as well as wind values and direction 
of fire, scroll to MV and adjust to your best estimate of 
your gun’s muzzle velocity.

 

» Select MV to enter the MV sub menu. Scroll to and 

select Cal MV.

 

» The Cal MV range is the suggested target distance 

at which to calibrate. For best results, find a range 
where you can shoot to between 90% and 100% of the 
recommended range but no further.  Calibrating at less 
than 90% of the recommended range will lessen accu-
racy and less than 80% or beyond the recommended 
range will not be valid.

 

» Adjust Range to match the actual distance to your 

target where you are shooting. Accuracy here is key! 
Use a quality ranger finder if you are not on a measured 
range.

 

» Apply the suggested elevation hold shown in Drop in 

your scope turrets or reticle.

CALIBRATING MUZZLE VELOCITY

 

» Take a number of shots to determine the actual 

bullet drop. Adjust Drop to match the actual 
observed bullet drop of the bullet at that range. 
For example, if the point of impact is 1.5 Mils 
below the bullseye adjust the Drop value to be 
1.5 Mils greater. 

 

» A new MV will be automatically calculated to 

match the actual impact of your round.  (In this 
example, the MV will be decreased.)  No chrono-
graph required!

 

» A (+) or (-) in front of the MV value indicates the 

new MV has been calibrated up or down.

 

» Exit to accept the new MV value.

Note! The suggested MV Cal range is the distance where the bullet 
slows to Mach 1.2. If the suggested range cannot be matched it 
is better to shoot at a shorter/closer distance rather than further. 
However, as the MV calibration range decreases, so does MV 
calibration accuracy. Try to shoot as close to the recommended 
MV Cal range as possible.

Note! If the MV-Temp table has been populated, MV values 
will be locked by the MV-Temp table and MV values will not be 
automatically adjusted by the MV Cal procedure above.
