Type of Course
: Single Target
Targets (type & number)
: Birchwood Casey, Dirty Bird® 12" x 18" Silhouette Target or equivalent (Here’s an example

Yards, Sixth String - 5 Yards
Shot “Time Window”
: First and Sixth Strings are allotted the minimum time window per class. Second String “Time Window” is double the First - Third String double the Second, etc.
Example - Expert “Time Windows”:
1st String = 1.5 Seconds
2nd String = 3.0 Seconds
3rd String = 6 Seconds
4th String = 12 Seconds
5th String = 24 Seconds
6th String = 1.5 Seconds
Weapon ready condition
: Each String begins with the weapon in identical condition (including any optics), loaded, with a round in the chamber, on safe at “low ready”.
: After an audible start signal, disengage safety and fire up to 5 shots into the target or until audible stop signal. Shots
fired outside the allotted time incur a penalty - “minus 10 pts.” The weapon must be returned to “safe” condition after each string. The range officer may
require a weapon to be unloaded after a string, prior to changing position, at their discretion.
**Violation of range officer safety directions, or “unsafe handling” disqualify any score.**
: Score the target for points, subtracting 10 points for each shot taken outside of the given time window.
: Scoring of 285 or better, 5 times in any 2 year period results in an automatic change to the next highest available
class. Scoring a single “300” in any 2 year window likewise requires that a shooter immediately move to the next higher class.
