Example 2: Take the same size target but now the Mil reading is .75 (from crosshair intersection to bottom of ﬁrst Mil Dot).

Known size of target: 12”x 12”

Mil Reading: .75 Mil

12 X 27.778

.75 Mil

CONVERTING TRAJECTORY DATA TO MIL HOLDOVERS

To calculate holdovers you must ﬁrst obtain your round’s trajectory data. Look at the ammunition manufacturer’s website, in a

manufacturer’s brochure, or use a ballistic software program. You will need the Bullet Path data for a 100-yard zero, in hundred-yard

increments.

The following ballistic information example refers to the Federal .308 168-gr. BTHP Match Round and a 100-yard zero. The left column

lists the cartridge’s trajectory in inches at 100-yard increments. The next column contains the mil-size in inches at these same

distances. Divide the trajectory by the mil size at each distance to ﬁnd the holdover in Mils.

= 444.44 Yards
