    BORE SIGhTING AND ZEROING ThE SCOPE Bore sighting is a preliminary procedure to achieve proper alignment of the scope with the rifle bore. It is best done using a Bushnell Bore Sighter. If a bore sighter is not available, it can be done as follows: Remove the bolt and sight through the gun barrel at a 100 yard target.
  • Page 8 In the example to the left using the BTR-Mil reticle, the shooter was attempting to hit a target in the center of the crosshairs. The actual point of impact hit 4 Mils down and 3 Mils left, as indicated by the red dot. Adjust the elevation dial 4 Mils up/windage dial 3 Mils right.

    Rotate the elevation turret knob counterclockwise to move the reticle plane up, or clockwise to move it down. Rotate the windage dial counterclockwise to move the reticle plane right, or clockwise to move it left. These Bushnell Tactical Riflescopes provide 5 mils of adjustment per complete revolution of the turret.

  • Page 14: Using The Mil Dot Reticle (Et3124F / Et6245F)

    USING ThE MIL DOT RETICLE (ET3124F / ET6245F) Your Bushnell riflescope contains a mil-dot reticle (1st focal plane), the most accurate means of range estimation using a manual optical device. These mil dots also allow precise leads for moving targets and exact compensation for shooting in a crosswind.
  • Page 15 height or width carefully in mils, compute it according to the formula and you will find its range. Support your rifle and be precise when measuring objects; any measuring error causes an error in the computed range. Equally, a mistake in estimating the object size results in a proportional range error.

    USING ThE BTR-MIL™ BALLISTIC TACTICAL RETICLE (ET3124FJ / ET6245FJ) The Bushnell BTR-Mil™ Ballistic Tactical Reticle is a hashmarked reticle that uses mrad based subtension lines for ranging, holdover and windage corrections. The illuminated 1 mil diameter circle with .1 mil center dot provides an unobstructed view of the target with 10 illumination settings.

    USING ThE BTR-1 TACTICAL RETICLE IN A FIRST FOCAL PLANE SCOPE (ET1624F) Elite Tactical model ET1624F with the BTR-1 Tactical Reticle is designed to be sighted-in at 100 yards (or meters), and provides hold over points out to 600 meters. This reticle is calibrated for use with 223 Rem/5.56 ammunition loaded with 55-62 grain bullets. Because the BTR-1 reticle is located in the first focal plane (FFP) position in this model, it will be accurate for all targets at any magnification setting.

  • Page 26 MAINTENANCE Your Bushnell Elite Tactical riflescope, though amazingly tough, is a precision instrument that deserves reasonably cautious care. 1. When cleaning the lenses, first blow away any dry dirt and dust, or use a soft lens brush. Fingerprints and lubricants can be wiped off with lens tissue, or a soft clean cloth, moistened with lens cleaning fluid.
