All of
the professional lit-reticle riflescopes have a built in adjustment that
compensates for bullet drop. The elevation dial is calibrated for bullet
drop in increments from 100 yards to 500 yards. This innovation eliminates
the need for complicated ballistic calculations and puzzling aiming
patterns. In case the user needs to take a shot at different distances,
the alignment process is simplified to the quick turn of a knob.
Bullet
drop compensation is only possible for certain caliber's, with specific
weights and muzzle velocity:
