The Winchester Xpert Sporter SR rifle in .21 Sharp with a threaded 16.5-inch barrel (brand part no. 5252141003) is a bolt-action rimfire built around the newer high-velocity .21 Sharp cartridge with a suppressor-ready muzzle. Winchester threads the barrel 1/2-inch by 28 TPI, and a 10-round magazine compatible with the 10/22 pattern gives quick reloads. The 1-in-12 rate of twist is matched to the cartridge for consistent accuracy. Among threaded-barrel bolt action rifles, this Xpert Sporter SR configuration favors shooters who want a suppressor-ready modern rimfire cartridge with magazine flexibility.
