BC
-49.5 to -52 inches 200 Yards
ABC
More than -52 inches of path height (if the path height is more than 64 inches, performance
will be reduced by the difference)
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.
Extreme Long Range Group Selection ā
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.
