Leupold’s TMR uses a mil dot style framework that incorporates a milliradian-
based subtension scale for ranging known targets. In addition, the intersection
of the crosshair is left open, creating a small, clear aperture for increased preci-
sion at longer ranges. Recent findings have determined that existing reticle
designs obscure the target at longer distances. The TMR reticle eliminates that
problem.
FIRST VERSUS SECOND FOCAL PLANE
In variable-magnification optics, the magnification setting for the use of the
Mil Dot or TMR reticle is determined by whether the reticle is in the first or sec-
ond focal plane. The easiest way to determine if the reticle is in the first focal
plane is to view the reticle through the scope while changing the magnification
setting. If the size of the reticle appears to change as the magnification setting
is changed, the reticle is in the first focal plane. If it does not appear to change
size, it is in the second focal plane. If the reticle is in the first focal plane, no
specific magnification setting is required to obtain the proper subtension to
yield accurate range estimating results.
