Franklin Armory is now selling what may be the first gas-operated, semi-automatic rifle chambered for the .17 WSM (Winchester Super Magnum) cartridge. The F17-L rifle uses a Stoner-like system with direct gas impingement and a rotating locking bolt. Although it is a rimfire cartridge, the .17 WSM runs at centerfire rifle velocities. Factory ammo is rated up to 3,000 fps with a 20 grain bullet.
