Horus® - Leupold

The base scale for Horus reticles is .1 milliradians. The scale can be visually subdividedand/or combined by a trained user to produce infinite milliradian referencecombinations for limitless target ranging, leading, or holdover precision.Since the holdover features are presented in milliradian increments, they can becorrelated to any ballistic trajectory or used to estimate windage and lead movingtargets in the same manner as all milliradian based reticles.To use a Horus reticle simply determine the range to the target using the milsystem, then use the corresponding aiming point that is matched to your cartridgeto engage the target.FIRST VERSUS SECOND FOCAL PLANEAll Horus reticles located in the first/front focal plane provide accurate subtensionvalues regardless of the magnification setting used. The easiest way todetermine if the reticle is in the first focal plane is to view the reticle throughthe scope while changing the magnification setting. If the size of the reticleappears to change as the magnification setting is changed, the reticle is in thefirst focal plane. If it does not appear to change size, it is in the second focalplane. If the reticle is in the first focal plane, no specific magnification settingis required to obtain the proper subtension to yield accurate range estimatingresults.4
