The primary high-power rifle competition is the 88 round National Match Course (NMC). This course is defined by NRA rules, and includes two sighting shots at each stage, and consists of twenty shots fired from the standing position, slow-fire at 200 yards; twenty shots fired from the sitting position, rapid fire at 200 yards; twenty shots from the prone position, rapid fire at 300 yards; and twenty shots fired from the prone position, slow fire at 600 yards. The STMTC does not have a range that extends to these distances so we fire the match at 200 yards, 300 yards, and 500 yards at the Central Texas Silhouette Association range near New Braunfels.
There are two basic disciplines for shooting the NMC, Service Rifle and NRA Match Rifle. Service Rifle requires the use of a rifle that is almost identical to the current U.S. service rifle. This is the M16 or its commercial equivalent the AR15 (However the M14 or its commercial equivalent the M1A is also allowed). NRA Match Rifle allows the use of any rifle chambered for almost any cartridge and equipped with metallic sights. Bolt action rifles are common in Match Rifle, but the AR15 with major modifications is prevalent.
The STMTC frequently is well represented at Texas State Rifle Association (TSRA) matches held around the state and some members participate in the National Matches at Camp Perry, Ohio annually. Other shooting organizations holding matches at the full distances are located in Carthage, Beaumont, Houston, and Mineral Wells. High Power is divided into two categories.
• Service Rifle, which uses a centerfire rifle configured as a U.S. military service rifle and using service iron sights such as the M1, M14, and M16.
• Match Rifle, which uses any centerfire rifle with metallic sights and a magazine capable of holding not less than five rounds, such as the Winchester Model 70, Remington 40X, and the AR-15 based space-guns.
The standard NRA courses of fire consist of four separate matches shot in three different shooting positions at three different distances.
