ELEVATION AND WINDAGE TURRETS
The turrets of the Bushnell® Elite® Tactical Riflescope provide audible and visual references. Each turn of the turret provides an audible “click” which coincides with a movement of the visible reference point on the turret knob. Additionally, clicks can be felt by your fingers as the turret knob moves. Each “click” represents .1 mil.
The Bushnell Elite Tactical Riflescope features T-Lok be rotated in either direction to make appropriate adjustments. After adjustments are made, the turret can be pushed back into the downward position to prevent movement, or left elevated and ready for further adjustments if preferred.
With the turrets pulled fully upward, 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.
After adjustments have been made, you can reset the turret to zero by following the steps below:
1. Ensure the turret is in the lock position.
2. Use a coin or flathead screwdriver to remove the turret screw found on top of the turret knob, being careful not to displace the o-ring found under the turret knob.
3. Remove the turret knob and return it to the turret, with the “zero” mark on the knob lining up with the vertical index line on the turret.
4. Return turret screw to top of knob and tighten down, making sure the turret knob is in the locked position so the turret knob does not turn while tightening the screw.

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. The eyepiece has a large adjustment range and should be used in
conjunction with the side focus (parallax) adjustment to obtain maximum resolution when viewing targets at long ranges.
POWER CHANGE RING
Changing the magnification of the Bushnell Elite Tactical Riflescope can be accomplished by grasping the knurled knob marked with the scope’s magnification range (located on the far end of the ocular bell end). Turn the power change ring clockwise for higher magnifications, counterclockwise for lower magnifications. The magnification setting can be identified by noting the number that is in front of the stationary dot on the scope tube.
SIDE FOCUS
The Side Focus adjustment corrects Parallax error. Parallax error is experienced when the intended target and the reticle are not on the same focal plane. The side focus adjustment relocates an optical element within the scope, manipulating the incoming image to appear on the same focal plane as the reticle within the riflescope, thus eliminating parallax error. Parallax error results in inconsistencies regarding point of impact. This can be best experienced by looking at a 100 yard target with the side focus set to 500 yards. While slightly moving your head left and right, or up and down, you will notice movement at the location where the crosshairs intersect. However, if you change your side focus adjustment to 100 yards while looking at the 100 yard target, the intersection of the crosshairs will not move. Please note the distance markings on the dial are intended as reference points only. Exact side focus adjustments may
needed after making adjustments to the eyepiece in order to achieve a high resolution, parallax free image.

FIRST FOCAL PLANE RETICLE
The Bushnell Elite Tactical Riflescopes covered by this manual have their reticles located in the first focal plane. Therefore, the reticle will increase in size when the magnification is increased. This feature allows the continued use of the mil measurement system contained in the reticle, regardless of the power setting. Second focal plane reticles restrict the user to making measurements at a specific power, as the reticle remains the same size and will not account for different magnification levels.
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 sight is not available, it can be done as follows: Remove the bolt and sight through the gun barrel at a 100 yard target. Then sight through the scope and bring the crosshairs to the same point on the target using the turrets or windage adjustments. Return the bolt and prepare to shoot down range at the 100 yard target.
Your next step will be to zero the scope using live rounds. Fire your first shot and note the location of impact. You can use the turrets to change the point of impact accordingly. For example, if your first shot went 1 mil high and 1 mil left, adjust your elevation dial down 1 Mil and your windage dial 1 mil right. Always adjust in the opposite direction from your point of impact.
As you fire your second shot, you should see the point of impact hit closer to your intended target. Multiple rounds may need to be fired before achieving consistent results. You may also use reticle within your scope to help decipher the correct adjustments. The following page shows how this works, using the H59 reticle as an example.

In the example to the left using the H59 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 indicated by the red dot. Adjust the elevation dial 4 Mils up/windage dial 3 Mils right. Another way to look at this is to determine what adjustment needs to be done with the turrets to move the red dot so it is centered in the middle of the crosshairs.

BUSHNELL MIL DOT RETICLE
The Bushnell Mil Dot Reticle provides a total of ten Mils on both the vertical and horizontal crosshairs. One Mil is measured from the middle of one dot to the middle of the next dot. The last Mil on the outer edges portion of the horizontal and vertical crosshair is measured from the center of the fourth Mil Dot from center to the edge of the thick line. You will notice the intersection of the crosshairs does not contain a Mil dot. This is to allow maximum target acquisition without interference from the reticle.
The space from center-dot to center- dot is one mil, which is an angular measurement that widens with distance. One mil at 100 yards equals 3.6 inches, at 1000 yards, that same one mil will have widened by ten times to 36 inches. The distance is ten times further, so the mil represents a space that’s ten times larger.
The Bushnell Elite Tactical scope features the Mil Dot reticle in the FIRST FOCAL PLANE. The reticle is placed after the magnification portion of the scope tube and results in both the target and reticle increasing or decreasing in size with different magnification levels. The first focal plane reticle will maintain accuracy regarding Mil Dot measurements. This design syncs the measurement of the Mil Dot in the scope with each power throughout its range thus; Mil Dot measurements can be used within any power of the scope. Some scopes have the Mil Dot reticle in the second focal plane. Second focal plane reticles do not change in size with a magnification change and therefore the measurements do not coincide. Second focal plane Mil Dot reticles will only provide a reference at a specific magnification.

USING THE MIL DOT RETICLE FOR RANGING
The Equations:
Size of target in yards X 1000 Size of Target in Mils
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
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. What is my distance to the target?
Known size of target: 12”x 12” Mil Reading: 1Mil
= Range in Yards
= Range in Yards
= Range in Meters
12 X 27.778 1 Mil
= 333.33 Yards
