Wyoming's Top 100 - Centerfire Pistol (The “150” Course of Fire) Rules

Type of Course: Single Target

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

Setup: Target set securely in target stands (or on a designated backstop) at chest height. Markers on range clearly indicating
shooting locations for each string of fire.

No. of rounds to be scored: 15

Maximum points: 150

Pistol must conform to USPSA production class, however high-capacity magazines may be used.  

Start position: First String - 5 Yards, Second String - 10 Yards, Third String - 25 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.

Example - Expert “Time Windows”:
1st String = 3.0 Seconds
2nd String = 6.0 Seconds
3rd String = 12 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”.

Procedure: 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.**

Scoring: Score the target for points, subtracting 10 points for each shot taken outside of the given time window.

Classification: Scoring of 120 or better, 5 times in any 2 year period results in an automatic change to the next highest available
class. Scoring a single “150” in any 2 year window likewise requires that a shooter immediately move to the next higher class.

Class String 1 String 2 String 3
Novice 10 sec. 20 sec. 40 sec.
Intermediate 5 sec. 10 sec. 20 sec.
Expert 3 sec. 6 sec. 12 sec.
