Be Accurate!

For the last six months my nephew and girlfriend have belonged to and participated in a local Crossbow club. They have been envolved in club activities consisting of basic firing and non-firing exercises. However, none of this training covered the calibration and use of the crossbow scope.

This weekend they went out and purchased state of the art, beautiful matching crossbows. They asked me about scope calibration, and I explained that the process is very similar to that used for a scope on a rifle. To expedite the calibration of their new crossbows, they were advised to use the following sequential procedures or process:

• While using the club’s indoor range, secure each crossbow with scope to a secure shooting rest and place out the standard bulls-eye targets 20 yards to the front.
• Identify each scope’s elevation and windage knobs. The elevation knob is located on the top of the scope and controls up/down movement. The windage knob is on the side of the scope and used to adjust right/left movement.
• Sight through the scope at the bulls-eye and fire three arrows. Adjust center of the shot-group for both windage and elevation. One click of windage and one click of elevation will move the center of the shot-group 1/20^th of an inch right/left and up/down. To move center of shot-group to the right and up, you would turn both windage and elevation knobs clockwise. Continue this process until center of the shot group has been adjusted to the center of the bulls-eye.

 Remove crossbows from the shooting rests, and while using good trigger squeeze/breathing techniques, fire groups of three arrows at the bulls-eye. Practice until each shot-group can be covered by a tennis ball.
