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.
