Bore Sighting

After mounting, an initial bore sighting of the Spitfire at short range
(25–50 yards) will save time and money at the range. This can be done
using a bore sighter according to the manufacturer’s instructions, or by
removing the bolt on some rifles and visually sighting through the barrel.

To visually bore sight a rifle:

1. Place the rifle solidly on a rest and remove the bolt.

2. Sight through the bore and center the target inside the barrel.

3. With the bull’s eye centered in the bore, make windage and elevation
adjustments until the center dot is aligned over the bull’s eye.

Final Range Sight-In

Final sight-in should be done at the range using the exact ammunition you
expect to hunt or shoot with:

1. After the Spitfire has been bore sighted, fire a shot or two at your
desired zero distance to check that you’re roughly on target. If necessary,
adjust the dot to put you near the center of the target (see Windage and
Elevation Adjustment on page 6).

2. Fire a three-shot group as precisely as possible.

3. Using the center of this group as a reference, make any necessary
adjustments for windage and elevation correction. Using arrows for
reference, adjust dials in the direction you wish the group to move.

4. Fire a final three-shot group to confirm proper adjustment. Repeat as
necessary.

The key thing to remember when shooting with the Spitfire is to keep
both your eyes open! Shooting with both eyes open allows you to take
full advantage of your peripheral vision to get on target very quickly.
Targets can be quickly centered within the dual rings and, if desired,
use the center dot for a more precise aiming point.

Note: If using an optional magnifier for distance shooting, you
may find it easier to shoot with one eye closed due to the increased
magnification.
