MUZZLE VELOCITY (MV) CALIBRATION

The most important input for calculating accurate Applied Ballistics solutions is getting your

MV correct. You need to either chronograph your firearm or use the embedded MV Calibration

routine built into the BDX App. To use the MV Calibration routine make sure your scope is

zeroed (i.e. at 100 yards) and verify that the BDX App is showing zero holdover values at the

zero distance by ranging the target at the zero range and verifying the your holds are in fact zero

Use the MV Calibration routine at the

farthest distance you intend to shoot.

The greater the distance the more

accurate the MV calculation will be.

In this example the target was at 378

yards. Confirm your max target range.

Note – ABU only provides ballistic

solutions out to 800 yards maximum.

Now enter the elevation offset between point of impact and point of aim and select CONFIRM.

In this example the 3 shot group was 7 inches low. A new MV of 2477 fps was calculated.

Select YES to confirm and this MV will now be used for ballistic solutions going forward. See the

confirmation dialogue box in the image below right.
