In the sport of biathlon, because shooting speed is an important performance factor and semi-automatic guns are illegal for race use, straight-pull actions are quite common, and are used almost exclusively on the Biathlon World Cup. The first company to make the straight-pull action for .22 caliber was J. G. Anschütz; the action is specifically the straight pull ball bearing lock action, which features spring-loaded ball bearings on the side of the bolt which lock into a groove inside the bolt's housing. With the new design came a new dry-fire method; instead of the bolt being turned up slightly, the action is locked back to catch the firing pin.
