The breech is opened by the breechblock moving in-line with the axis of the barrel and is locked in the closed position by an obstruction such as a cam, wedge, pawl or levers. A roller lock is commonly associated with firearms produced by Heckler & Koch. This type of breechblock can be adapted to cycle by lever, cocking handle, gas or recoil.
Although breech-loading firearms were developed as far back as the early 14th century in Burgundy and various other parts of Europe, [3] [4] breech-loading became more successful with improvements in precision engineering and machining in the 19th century. The main challenge for developers of breech-loading firearms was sealing the breech.

Two years prior to the NATO adoption of the 7.62×51 mm NATO T65 in 1954, Winchester (a subsidiary of the Olin Corporation) branded the round and introduced it to the commercial hunting market as the .308 Winchester. The Winchester Model 70 and Model 88 rifles were subsequently chambered for this round.
All of the WSM cartridges are inspired on the .404 Jeffery non-belted magnum cartridge which is shortened to fit a short rifle action (such as a .308 Winchester). [1] It was developed by Rick Jamison in 1997-1998 as proven in a 2005 lawsuit Jamison vs. Olin Corporation-Winchester division. [2] Jamison was given 7 patents on the cartridge design.
