Press one button and the G7 BR2 measures range, pressure, temperature, and incline to calculate a drop and wind solution based on your programmed Ballistic Coefficient (G1 or G7), Muzzle Velocity, Sight Height and Zero Range.  Use the MOA or MRAD outputs with any scope’s adjustments to dial-in the angular solution. In BDC mode, compatible with ballistic reticles and BDC turrets which are calibrated to a fixed temperature and altitude, the BR2 will calculate a corrected solution automatically adjusted for varying conditions- just dial your BDC turret to the displayed Shoot-To-Range. You will never need to swap out your turret again.
