Inclined shooting: calculation

Equation

To manually calculate inclination adjustment, we only need to know our typical bullet drop for the target distance and our angle of fire:

BDA * cos(angle°) - (.01 * angle°) = Adjusted vertical hold in MRADs

Where:

• BDA = bullet drop adjustment

Data collection

Angle of fire can be determined by opening the in-game firing angle indicator using Shift+Ctrl+K. Unadjusted bullet drop information can be found on the in game range card or collected prior to operation start as D.O.P.E.

Calculation example

Sgt McShooty is deployed as a Spotter (Manual) on a Honeybadger. He ranges a priority target at 900m with an inclination of 20°. Looking at his range card, he notes he would typically need to adjust 9.8 MRADs up for this range.

9.8 * cos(20°) - (.01 * 20) = 9.0 MRADs

The adjusted vertical hold for 20° of inclination is 9.0 MRADs.

Equation limitations

This equation will serve well under most conditions and the small degree of inherent error will not impede operations in target rich environments or in high value target environments.
