TBR FOR RIFLE USERS (RX-1000 i TBR MODELS ONLY)
TBR calculates the equivalent horizontal range (level fire range) from which
you can determine the correct aim for the conditions . For example, if you
are shooting a .270 caliber, 130 grain bullet at 3,050 feet per second up a 30°
incline at 400 yards, direct line of sight, the TBR output will be 367 yards . The
first step in correctly using TBR is to Practice, Practice, Practice . Anytime you
handle a firearm or bow, you are ultimately responsible for your projectile .
