Some sniper rifles were used during the Korean War. The P14/No3Mk1 was declared obsolete in British service in 1947. Surplus P14s were sold throughout the Commonwealth, especially Canada, New Zealand, Australia and South Africa, where they proved popular for full-bore target shooting, and being sporterised for game shooting. Adapting the design to fire the standard .303 British round led to the Rifle, .303 Pattern 1914 (P14), a design fed from a five-round internal box magazine. With its prominent sight protection ears on the receiver, "dog-leg" bolt handle and "pot-belly" magazine, it was distinctive in appearance. The action was essentially a Mauser design with some Lee–Enfield features and optimised for rapid fire, with the action cocking on closing, a feature highly valued by the British Army with its emphasis on riflemen highly trained for rapid fire, but less valued in other armies, such as the US or Germany, where cock-on-opening designs such as the M1903 Springfield and Gewehr 98 were preferred. Cock-on-opening actions became more difficult to operate when heated by rapid fire as the effort to open the bolt had to overcome the striker spring to cock the action as well as unsticking the fired case from the chamber. The P14 was an advanced design for the time, and was said to be the most advanced service rifle of World War I. The Pattern 1914 Enfield had a large, strong bolt action made from nickel-steel, and the bolt travel is long, as it was designed for the dimensionally large and powerful .276 Enfield cartridge. The bolt action had a Model 98 Mauser type claw extractor and two forward lugs; there was also a rear safety lug formed by the base of the bolt handle sitting in a recess in the receiver. Much faster and smoother to operate than a Model 98 Mauser, the bolt was well-supported throughout its travel and the camming action on opening and closing the bolt facilitated ease and speed of operation. The unusual 'dog-leg' shaped bolt handle is low profile and places the bolt knob just rearwards of the trigger close to the firer's hand, again facilitating rapid cycling and fire. Like the Lee–Enfield, the safety falls under the firer's thumb and can be operated silently. Due to the original Pattern 1913 Enfield action being designed around the high-powered .276 Enfield experimental cartridge with a larger diameter case than the .303 British, the internal box magazine capacity for the smaller diameter .303 British was six rounds, although the employed stripper clips held only five cartridges.
