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 that rimfire sporter matches at SLSC are not CMP-sanctioned so we allow some leeway with regard to match rules and procedures, e.g. starting position, trigger pull weight, required ammunition, alibi reshoots, etc.

SLSC Rimfire Sporter Match Report

August 9th, 2025

We were hoping for cooler weather after last month’s steambath, and surprisingly, we got it—with perfectly pleasant conditions for the August Rimfire Sporter match at Sanner’s Lake!  The battle for the top spot once again started off as a nail-biter, with Greg Banta roaring out of the gate with a strong prone performance.  As the match went on, however, Andrea Swierczek clawed her way back from a five-point deficit by putting in a strong standing performance and cruised to victory with an excellent 574-16X.  Congratulations to Andrea!  See all the scores and details in the match report linked below.
