We have had somebody firing unauthorized rounds in the Indoor Range. This has to stop now. The ONLY rifles that are allowed on the Indoor Range are rifles that shoot a rimfire .22 caliber or rifles that shoot a pistol caliber 9mm cartridge, commonly called a Pistol Caliber Carbine. AR-15 Platforms that shoot .223 or 5.56 or any other caliber other than .22 rimfire or 9mm Pistol cartridge are NOT ALLOWED. Bullets that have a steel core are NOT ALLOWED. If you see anyone shooting unauthorized rounds in the Indoor Range, please ask them to stop and report it to the office and/or to Warren Pratt.
