FUNCTION 2: TWENTY-FIVE RIFLE BALLISTICS GROUPS
(TBR MODELS ONLY)
TBR includes ballistics settings for twenty-five cartridge groups which are displayed
as 1 through 25, specifically formulated for the four functions of TBR. For
example, if your cartridge type is in Group 3, the displayed reading will account
for the shot angle and provide the proper distance for holdover purposes (see
following chart). You must choose one of the twenty-five groups, based on
your cartridge and ballistics information. The cartridge table shows a common
assortment of factory loads organized in their TBR performance groups. If you
are shooting a similar bullet weight and muzzle velocity that falls into the
provided selections, you can use that cartridge group with full confidence.
