THE LEUPOLD SPECIAL PURPOSE RETICLE (SPR)
The Leupold Special Purpose Reticle (SPR) was designed to allow users to suc-
cessfully engage targets with greater flexibility than generally possible with
other reticle styles. This reticle also preserves the instinctive fire capabilities of
the Leupold Circle Dot reticle in short range, low magnification engagements
typical of 3-gun competition and Close Quarter Battle in the 21st century. This
unique blend of capabilities allows the various optics platforms equipped with
this reticle to perform equally well in open desert, heavy cover, or the urban
environment.
A key component in the operation of the Leupold Special Purpose Reticle is
the ability to estimate range using the milliradians (mils) scale. A milliradian is
a unit of measure that corresponds to different distances at different ranges.
For example:
The subtension of 1 mil equals 3.6 inches at 100 yards or 36 inches at 1,000
yards. In metric units, the correspondence is 1 mil equals 10 centimeters at 100
meters or 1 meter at 1,000 meters. Knowing this subtension and knowing the
size of the target (or a reference object near the target) allows the distance to
the target to be estimated with considerable accuracy.
The SPR Reticle is comprised of three heavy posts connected by fine
stadia lines, much like the German #4 reticle. On the fine stadia,
