In firearm designs, the term single-shot refers to guns that can hold only a single round of ammunition inside and thus must be reloaded manually after every shot. Compared to multi-shot repeating firearms ("repeaters"), single-shot designs have no moving parts other than the trigger, hammer/firing pin or frizzen, and therefore do not need a sizable receiver behind the barrel to accommodate a moving action, making them far less complex and more robust than revolvers or magazine/belt-fed firearms, but also with much slower rates of fire.
The M24 Sniper Weapon System (SWS) or M24 is the military and police version of the Remington Model 700 rifle, M24 being the model name assigned by the United States Army after adoption as their standard sniper rifle in 1988.

The .243 Winchester (6×52mm) is a popular sporting rifle cartridge. Developed as a versatile short action cartridge to hunt both medium game and small game alike, it "took whitetail hunting by storm" when introduced in 1955, and remains one of the most popular whitetail deer cartridges.

The .243 is based on a necked down .308 Winchester, introduced only three years earlier. Expanding monolithic copper bullets of approximately 80 to 85 grains or traditional lead rounds of 90 to 105 grains with controlled expansion designs are best suited for hunting medium game, while lighter rounds are intended for varmints.

The M2010 Enhanced Sniper Rifle (ESR), formerly known as the XM2010 and M24 Reconfigured Sniper Weapon System, is a sniper rifle developed by PEO Soldier for the United States Army. It is derived from and replaced the M24 Sniper Weapon System, and was designed to give snipers longer range in the mountainous and desert terrain of the War in Afghanistan. After winning a competitive bidding process, Remington was awarded the production contract for up to 3,600 weapons. The Army had anticipated sending the upgraded weapons to deployed snipers in late 2010, but later expected fielding would happen in January 2011. The M2010 fires .300 Winchester Magnum (7.62×67mm) ammunition, which offers about 50 percent more effective range than the M24's 7.62×51mm NATO. This chambering to dimensionally larger cartridges is possible because the M24 was designed to use the "long action" bolt version of the Remington 700 receiver for cartridges up to 3.34 inches (84.84 mm) in overall length.
