Fast Focus Eyepiece The fast-focus eyepiece dial is found on the ocular end of the Bushnell Elite Tactical Riflescope. Use this adjustment to obtain a reticle image that appears sharp to your eyes. If adjustment is needed, look at a distant object for several seconds without using your scope. Then, shift your vision quickly, looking through the scope at a plain background. Turn the fast-focus eyepiece dial clockwise or counterclockwise until the reticle pattern is sharp and clear.
Please note the distance markings on the dial are intended as reference points only. Exact side focus adjustments may be needed after making adjustments to the eyepiece in order to achieve a high resolution, parallax free image. First Focal Plane AND SECOND FOCAL PLANE RETICLES Some models of Bushnell Elite Tactical Riflescopes described this manual have their illuminated reticles located in the first focal plane, while others place the reticle in the second focal plane.
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. Another way to accomplish this is to return the weapon to the original aiming point on the target. Ensure that it is securely held in place.
Elevation and Windage TARGET Turrets (3-12x44 & 6-24x50 models) Selected models of Bushnell Elite Tactical Riflescope with illuminated reticle feature target style adjustment turrets, which provide audible and visual references. The turrets can be rotated in either direction to make appropriate adjustments. Each turn of the turret provides an audible “click” which coincides with a movement of the visible reference point on the turret knob.

Elevation and Windage FINGER TOUCH ADJUSTMENTS (1-6.5x24 models) 1-6.5x24 models of the Bushnell Elite Tactical Riflescope with illuminated reticle feature finger-adjustable, audible-click elevation and windage adjustments. To adjust the elevation or windage: 1. Remove the covers from the Elevation and Windage Adjustments. 2. Grasp the Adjustment Knob and turn it in the appropriate “UP” (and/or “R”) direction indicated by the arrows. Each “click” will change the bullet impact by .1 mil or approximately .
Elevation and Windage T-LOK™ Turrets (ET18524) The model# ET18524 Bushnell Elite Tactical Riflescope features T-Lok™ (locking) turrets, which provide audible and visual references. When a turret is lifted (elevated) into the upward position it can be rotated in either direction to make appropriate adjustments. Each turn of the turret provides an audible “click” which coincides with a movement of the visible reference point on the turret knob.

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. RETICLE DESCRIPTION The middle of this reticle contains four evenly spaced mil-dots arrayed outward vertically and horizontally from the center.
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. Here’s an example: A coyote is sunning himself in a snowfield beside a fencepost; having crossed the fence earlier, you know that the post is four feet high, or 1.33 yards. The fencepost measures 2.
The Mil Dot Reticle Measurement System in the First Focal Plane Applies at any Magnification Level. 2 Mils at 12x (100 yards) 16 2 Mils at 3.
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. In order to facilitate accurate holdover and windage compensation, this reticle uses hash marks spaced in 1 mil increments with .5 mil graduations.
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.

USING THE BTR-1 tactical RETICLE IN A SECOND FOCAL PLANE SCOPE ( ET1624SF) Elite Tactical model ET1624SF with the BTR-1 Tactical Reticle is designed to be sighted-in at 100 meters/yards, 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. The reticle design allows accurate aiming points out to 600 meters.

USING THE BTR-2 tactical RETICLE IN A FIRST FOCAL PLANE SCOPE (ET1624J / ET18524) The BTR-2 reticle in first focal plane is an excellent choice for shooters needing maximum flexibility in a riflescope. This reticle in the first focal plane combines the close range benefits of a red dot sight with the long range capabilities offered by mrad based ranging reticle. The center horseshoe provides an unobstructed aiming point that is effective in both CQB scenarios and if targets are encountered at longer ranges.
Center dot measures .3 mils at highest power setting (6.5x or 8.5x, depending on model) BTR-2 @ 6.
USING THE BTR-2 tactical RETICLE IN A SECOND FOCAL PLANE SCOPE (ET1624SJ) The BTR-2 reticle in second focal plane is an excellent choice for shooters needing maximum flexibility in a riflescope. This reticle in the second focal plane combines an illuminated red dot with a mil hash platform. The center horseshoe provides an unobstructed aiming point that is effective in both CQB scenarios and if targets are encountered at longer ranges. At 6.
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. Microfiber cleaning cloths are also recommended. WARNING: Unnecessary rubbing or use of a coarse cloth may cause permanent damage to the lens coatings.
APPENDIX: MIL DOT RANGING & HOLDOVER EXAMPLES Using Mil Dot RETICLES for Ranging The Equations: Size of target in yards X 1000 Size of Target in Mils = Range in Yards Size of target in inches X 27.778 Size of target in Mils Size of target in inches X 25.4 Size of target in Mils = Range in Yards = Range in Meters Example 1: Looking through the riflescope, I located a preset target that has a known size of 12”x12” square. By using the Mil Dots I measured the target to have a Mil reading of 1.
APPENDIX: MIL DOT RANGING & HOLDOVER EXAMPLES Example 2: Take the same size target but now the Mil reading is .75 (from crosshair intersection to bottom of first Mil Dot). Known size of target: 12”x 12” Mil Reading: .75 Mil 12 X 27.778 = 444.44 Yards .75 Mil Converting Trajectory Data to Mil Holdovers To calculate holdovers you must first obtain your round’s trajectory data. Look at the ammunition manufacturer’s website, in a manufacturer’s brochure, or use a ballistic software program.

APPENDIX: MIL DOT RANGING & HOLDOVER EXAMPLES Using Mil Dot RETICLES for Holdover Once you know how to range your target with a Mil Dot reticle, and using the previous example, you can use the reticle instead of the turrets to make adjustments with holdover. For example, your range tells you that the 12” target is 300 yards away, (12”*27.778) / (1.1Mil). Based on the Federal .308 Win ballistic info in the previous example, you will need to hold 1.47 Mils down on the vertical crosshair and fire.
