The Ruger 10/22 autoloader requires only pulling the trigger to fire successive shots.

Most of the single-shot rifles that incorporate a moving locking block (either falling block or rolling block) have long since disappeared from the marketplace. In the late 1800s and early 1900s, there were numerous models of such rimfire rifles that were generally of a small-scale design. Replacing them were single-shot bolt-actions in which the bolt handle could be lifted out of its retaining notch and drawn back to open the chamber with the extractor pulling out the empty case. After a cartridge was placed in the chamber, pushing the bolt forward and turning the handle down into its locking notch closed the action. In some models, a cam moved the firing pin back to cock the action as the action was opened while in others the firing pin was held back by the sear as the action was closed. The first type is known as “cocks-on-opening” while the other is the “cocks-on-closing” type. In still other rifles, neither opening nor closing the bolt cocked the rifle. That was done after the action was closed by pulling back on a knob at the rear end of the bolt (the cocking piece).
