What rifle has the longest range?

As an expert in the field of firearms, I've spent considerable time studying the capabilities and specifications of various rifles. When it comes to discussing the longest range a rifle can achieve, it's important to clarify that range can be influenced by several factors including the type of ammunition used, environmental conditions, the skill of the shooter, and the rifle's design itself. The L115A3 sniper rifle, manufactured by Accuracy International, is known for its impressive range. It was reported that a British sniper used this rifle to set a record for the longest confirmed sniper kill, engaging targets at a distance of 2,475 meters (2,707 yards). This was a remarkable feat, as the rifle's effective range is generally considered to be around 1,500 meters (1,640 yards). However, the instance you mentioned, where shots took almost five seconds to hit targets at 900 meters (1,000 yards), is indeed beyond the recommended range for the L115A3. It's worth noting that while the L115A3 has demonstrated exceptional performance, there are other rifles that are designed to achieve even greater ranges. For instance, the Cheytac Intervention, chambered in .408 Cheytac or .50 BMG, is designed for anti-materiel and long-range shooting. The .408 Cheytac round, in particular, is known for its ability to maintain supersonic speeds at extended ranges, which can be crucial for long-range engagements. Another contender is the Barrett M82, or M107 as it's known in military service, which is a semi-automatic rifle that has been used for long-range engagements. It's chambered for the powerful .50 BMG round, which is capable of reaching targets at significant distances. The M82 has been reported to have been used effectively at ranges exceeding 2,000 meters (2,187 yards). Additionally, there's the McMillan Tac-50, which holds the current record for the longest confirmed kill in military history, made by a Canadian sniper at a distance of 3,540 meters (3,871 yards). This rifle is chambered for the .50 caliber round and is renowned for its precision and ability to deliver shots at extreme distances. When considering the longest range a rifle can achieve, it's also essential to consider the context. For military applications, the ability to engage targets at long ranges is crucial, and rifles like the ones mentioned are often used by specialized snipers. However, for civilian use or hunting, the need for such extreme ranges is less common, and the choice of rifle would likely be different. In conclusion, while the L115A3 is an exceptional rifle with a proven track record, there are other rifles designed for even longer ranges, such as the Cheytac Intervention, Barrett M82, and McMillan Tac-50. The choice of rifle for maximum range would depend on the specific application and the shooter's requirements.

Harrison killed the two Taliban machine gunners with shots that took the 8.59 mm rounds almost five seconds to hit their targets, which were 900 metres (1000 yd) beyond the L115A3 sniper rifle's recommended range. A third shot took out the insurgents' machine gun. The rifle used was made by Accuracy International.
