200 Yards
* If your bullet height path is less than -20 inches at 500 yards with a 200 yard sight-in, consider sighting-in at
300 yards and selecting group A or B . Alternately, you can use group C with a 200 yard sight-in, but the TBR
will be less accurate at extreme long ranges .
to activate the appropriate ballistics group, rFL must be
activated and you must choose between BaS, Moa, or HoLd.
once this has been done, pressing the Mode button will allow
you to select the appropriate ballistics group. GrP (Group) will
be shown in the upper display, and the current ballistics group
will be shown in the lower display. Press and release Power
repeatedly to scroll through the available ballistics groups.
Extreme Long Range Group Selection — If you intend to shoot varmints or targets at
ranges beyond 500 yards, selecting your group based on 800 yard performance will provide
a better performance match throughout this working range . Select your group for extreme
long range shooting from the table below .
