14 USING THE MIL DOT RETICLE (ET3124F / ET6245F) Y our 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.
15 height or width carefully in mils, c ompute it according to the formula and y ou will nd its range. Support your rie and be precise when measuring objects; any measuring error causes an error in the comput ed range. Equally , a mistake in estimating the object size r esults in a proportional range error .
16 The Mil Dot Reticle Measurement System in the F irst Focal Plane Applies at any Ma gnification Level. 2 Mils at 12x (100 yards) 2 Mils at 3.5x (100 yards).
17 USING THE BTR-MIL™ BALLISTIC T ACTICAL RETICLE (ET3124FJ / ET6245FJ) The Bushnell BTR-Mil™ Ballistic T actical Reticle is a hashmarked reticle that uses mrad based subtension lines for ranging, holdover and windage corrections. The illuminated 1 mil diameter circle with .
18 USING THE BTR-1 T ACTICAL RETICLE IN A FIRST FOCAL PLANE SCOPE (ET1624F) Elite T actical model ET1624F with the BTR-1 T actical 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.

26 MAINTENANCE Y our Bushnell Elite T actical riflescope, though amazingly tough, is a precision instrument that deserves reasonably cautious care. 1.
27 USING MIL DOT RETICLES FOR RANGING The Equations: Size of target in yards X 1000 = Range in Y ards Size of T arget in Mils Size of target in inches X 27.
28 Example 2: T ake the same size target but no w 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 .75 Mil CONVERTING TRAJECTOR Y DA T A TO MIL HOLDOVERS T o calcula te holdovers you must first obtain your round’ s trajectory data.

30 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.
