  • The .240 Flanged Nitro Express (FNX) is a powerful rifle cartridge designed for use in double-barreled rifles. It was developed in the late 1800s as an improvement over existing cartridges such as the .375 Flanged Nitro Express and the .500/.450 Nitro Express.The .240 FNX offers excellent performance at long range with low recoil and high accuracy. It is used for both hunting dangerous game, such as African buffalo and elephant, and long-range target shooting, making it a versatile choice for many types of hunters and shooters.The cartridge is available in popular bolt-action rifles from top manufacturers including Browning, Howa, Kimber, Remington, Ruger, Savage Arms and Tikka T3x CTR. It is also available in semi-automatic rifles such as the Ruger American Predator and Savage MSR 15 Competition.
