In this podcast, I discuss the formulas to determine distance using the reticle in your scope and just touching on the wind formula.
Milling Formula:
(target size) in inches x 27.77 / (target size in Mils)
10" target measuring .5 Mils wide
10 x 27.77 / .5 = 555.4 Yards
Milliradian-based Reticles
YARDS
Target Size (Inches) x 27.77 ÷ Target Size (Mils) = Distance (Yards)
10 (Inches) x 27.77 ÷ .2 (Mils) = 1,388 Yards
10 x 27.77 ÷ .2 = 1,388 Yards
Target Size (Yards) x 1000 ÷ Target Size (Mils) = Distance to Target (Yards)
2 (Yards) x 1000 ÷ .25 (Mils) = 800 Yards
2 x 1000 ÷ .25 = 800 Yards
METERS
Target Size (cm) x 10 ÷ Target Size (Mils) = Distance (Meters)
25.4 (cm) x 10 ÷ .5 (Mils) = 508 Meters
25.4 x 10 ÷ .5 = 508 Meters
Target Size (Inches) x 25.4 ÷ Target Size (Mils) = Distance to Target (Meters)
10 (Inches) x 25.4 ÷ .25 (Mils) = 1,016 Meters
10 x 25.4 ÷ .25 = 1,016 Meters
Target Size (Meters) x 1000 ÷ Target Size (Mils) = Distance to Target (Meters)
2 (Meters) x 1000 ÷ 2.8 (Mils) = 714 Meters
2 x 1000 ÷ 2.8 = 714 Meters
Minute of Angle-based Reticles
YARDS
Target Size (Inches) x 95.5 ÷ Target Size (MOA) = Distance to Target (Yards)
10 (Inches) x 95.5 ÷ 1.25 (MOA) = 764 Yards
10 x 95.5 ÷ 1.25 = 764 Yards
METERS
Target Size (Inches) x 87.3 ÷ Target Size (MOA) = Distance to Target (Meters)
72 (Inches) x 87.3 ÷ 5.5 (MOA) = 1,142 Meters
72 x 87.3 ÷ 5.5 = 1,142 Meters
Target Size (Meters) x 3438 ÷ Target Size (MOA) = Distance to Target (Meters)
Target Size (cm) x 34.38 ÷ Target Size (MOA) = Distance to Target (Meters)
