One additional feature provided within the Sig Ballistic App is the ability to calculate and set your muzzle
velocity and drop scale factor empirically by using actual bullet drop at known ranges. The suggested
ranges are based on your bullet selection. In this case select GUN PROFILES, then select a CUSTOM PROFILE
(223 Sierra FMJ shown) and then press the CALIBRATE button at the top right hand side of the screen:
Within the CALIBRATION sub menu you will now enter your known target ranges and drop at each range.
Once this information is input press the CALCULATE button and your results will appear similar to what
you see below. You will note that the default MV for this bullet was 2600 fps but the measured MV was
calculated to be 2624. You can now apply the calculated MV and DSF by pressing each button shown
below. Note – you can apply the calculated MV or DSF or both. The typical calibration process is to set
MV if you are shooting supersonic. If you are shooting subsonic it is suggested to apply both MV and DSF:
After inputting the actual drop data
as a function of known ranges, press
CALCULATE and then press SET MV
and SET DSF to apply your new MV
and DROP SCALE FACTOR for better
accuracy.
