• Waiting to unleash the GI in you? Wait no more! Consider our .17 HOT MAGNUM series your personal drill sergeant with a list of commanding features on the scope. Engineered with the revolutionary bullet-drop technology, these scopes are guaranteed to make you an extreme performer when it comes to the .17 Magnum Rimfire shooting. BULLET DROP TECHNOLOGY • To provide extreme accuracy for the .17 Magnum Rimfire caliber, the scope's elevation knob is precisely calculated to compensate for the elliptical drop of the .17 Magnum Rimfire with a 17 grain bullet. Once you complete the zeroing process at 100 yards , all you have to do is match the elevation turret indicator with 100 yds marking on the knob. From this point, your trajectory can be compensated for any yards from 100 up to 300 yards simply by turning the elevation knob to the desired setting
