Q

Ballistic Solutions

A

Calculated using ammo type, range to target, and the pitch and roll of the sight axis relative to the HP (measured by the inclinometer).

Ballistic tables are used to find the TE and drift angles, allowing for automatic ballistic control solution resulting in enhanced first round hit capability.
