Wyoming's Top 100 - Rimfire Rifle (The “300-mini” Course of Fire) Rules
Type of Course
: Single Target
Targets (type & number)
: Birchwood Casey Dirty Bird® 12" x 18" Silhouette Target
(please print equivalent target on an 11x17 or 8.5x11 sheet of paper
: 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
: First String - 5 Yards, Second String - 10 Yards, Third String - 25 Yards, Fourth String - 50 Yards, Fifth String - 100 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.
