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 .
