Rimfire Sporter Rifle Match

The Rimfire Sporter Match is a recreation-oriented competition using smallbore sporter firearms such as small game or "plinking" rifles commonly owned by almost all gun enthusiasts. This is a classic three-position match where all you need is a rifle and a couple of boxes of 22LR ammo, although additional equipment such as a shooting mat, extra magazines and a spotting scope are helpful. The course of fire is sufficiently straightforward such that new shooters can successfully complete it while experienced shooters will still find it interesting and challenging. Shooting  is done at 50 and 25 yards on a target with a 1.78" ten-ring and an 18" outer one-ring. The target is large enough for a beginner to hit within the scoring rings, yet challenging enough such that only one competitor in the history of the match has ever fired a perfect score. See below for more info including our upcoming matches. Additional info can be found in the CMP Rimfire Sporter Rifle Guide.  Note: rimfire sporter matches at SLSC are not CMP-sanctioned, therefore (at the match director's discretion) we allow some leeway with regard to match rules and procedures, e.g. starting position, trigger pull weight, overall weight, required ammunition, alibi reshoots, etc.

SLSC Rimfire Sporter Match Report

13 June 2026

We had a slight respite from the recent heat wave and that was enough to get five shooters out of the air conditioning and over to the Sanner’s Lake rifle range for the June Rimfire Sporter match.  And with decent weather came decent scores, as everybody scored in the 500’s with a few personal bests along the way.  New sporter shooter Frank Mazur also turned in a solid performance for his first time out, with iron sights no less!  Congrats to Frank and all the other shooters.  See all the scores and details below.  The next Rimfire Sporter match will be on 11 July—hope you can make it!
