Rimfire Sporter Rifle Match

The Rimfire Sporter Match is a recreation-oriented competition using smallbore sporter rifles 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 ammo, although additional equipment such as a shooting mat, extra magazines and a spotting scope are helpful. The course of fire is straightforward so that new shooters can successfully complete it while experienced shooters will still find it interesting and challenging. Firing 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, yet challenging enough 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 flexibility with regard to match rules and procedures, e.g. starting position, trigger pull weight, alibi reshoots, etc.

May 11th, 2024

Unusually cool and crisp weather greeted six shooters who made it out to the May Rimfire Sporter Match at Sanner’s Lake, the first such match of the 2024 season.  But it didn’t take long for everybody to blow the cobwebs off and get down to business, as the scores started climbing fast and furious!  Matt Reider notched a couple of quick 100’s to grab a 2 point lead early on and then held on for a nail-biter finish to take first place at the end of the day with an excellent 588-27X.  Further down the standings quite a few scores were in the mid-to-high 500’s keeping the competition tight across the board.  See all the scores and details below.
