Rimfire Sporter Rifle Match

The CMP Rimfire Sporter Match is a fun, recreation-oriented competition using smallbore sporter rifles (plinking and/or small game rimfire rifles) commonly owned by almost all gun enthusiasts. This is a unique 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 sufficiently straightforward such 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 simple enough for a beginner to hit, yet challenging enough that only one competitor in the history of the match has ever fired a perfect 600x600 score. See below for more info including our upcoming matches. Additional info can be found on the in the CMP Rimfire Sporter Rifle Guide.  Note that rimfire sporter matches at SLSC are not CMP-sanctioned so we have some flexibility with regard to match rules and procedures, e.g. starting in position, alibi reshoots, etc.

 Sanner’s Lake Rimfire Sporter Match Report

October 14th, 2023

The forecast was dismal but the raindrops held off and five shooters made the most of the dreary but dry conditions to sling lead downrange at the October Rimfire Sporter Match at Sanner’s Lake! As the last rounds impacted the terminal berm, the raindrops finally started, but everyone managed to get their gear stowed and the range cleaned up and back together before the downpours started. In the end, the cool and cloudy conditions made for some decent shooting, with excellent scores from top to bottom and even a few personal bests! See all the details in the match report link below.

This was our last Rimfire Sporter match of the year, so be sure to keep an eye on the SLSC calendar for next year’s schedule of matches and we’ll see you at the range in 2024!
