The NSSF Rimfire Challenge is designed to provide a fun gateway into the world of competitive shooting. The sport utilizes steel targets and .22 rimfire rifles and pistols. A rifle and a pistol are both required to compete.
.22 rimfire rifles, pistols, and ammunition makes entry into the sport inexpensive. .22 rimfire rifles and pistols are some of the most commonly owned firearms in the United States. .22 Long Rifle cartridges are the least expensive cartridges on the market. In the rimfire challenge, any commercially available .22 LR ammunition can be used. Fiocchi ammunition is often chosen for its reliability and accuracy.
The rimfire challenge is designed to be both safe and appealing to competitors and spectators. The action is fast and easy to follow. A distinct “Ping” is heard when the target is hit. Targets are spray painted white for each competitor, so hits are easy to see.
Eye and ear protection is required to be used by all participants, spectators and range workers.
The Rimfire Competition was developed with safety in mind. A course consists of at least 5 plates, and no more than 7 plates. Courses are completed without having to reload. As shooters run the course, they receive immediate feedback as to whether they have hit the targets or not.
Holsters are not allowed in this competition. This helps keep the price of entry low, and the emphasis on shooting instead of drawing. The courses are a challenge to shooters of all ages.
There are two basic categories, "Open" and "Limited". In the open category, pistols or revolvers with "scopes, optical sights, light gathering scopes, battery powered optics, lasers, compensators or muzzle brake" are allowed. In the limited category, iron sights, including adjustable sights and fiber optics, are allowed, but electronic sights, compensators, muzzle brakes or barrel weights are not.
Scoring. Targets are expected to be at least 8" in diameter, and easy to hit. Each target is scored as a hit or a miss. Each missed target adds two seconds to the score. The score consists of the time to complete the course. Firing is allowed until the targets are all hit or the firearm is empty.
Competitors fire each stage five times. The longest time is dropped, then the other four scores are added to give the score for that stage. The scores for all stages together are added to make the score for the match. The lowest score for the match wins.
