[26], According to JBM Ballistics,[27] using the 0.310 G7 ballistic coefficient provided by Bryan Litz, and a Weapon Employment Zone (WEZ) analysis of the XM2010 rifle with various .300 Winchester Magnum ammunition types by Bryan Litz, the MK 248 MOD 1 .300 Winchester Magnum cartridge, when fired at its nominal muzzle velocity of 869m/s (2,850ft/s), should have 1,286 to 1,289m (1,406 to 1,410yd) supersonic range under International Standard Atmosphere conditions at sea level (air density = 1.225kg/m3). By adding trajectories to the panel on the right you may produce charts and graphs that show the different trajectories side by side. This ammunition was developed as a .300 Winchester Magnum Match Product Improvement (PIP) and uses the 220 gr (14.26 g) Sierra MatchKing Hollow Point Boat Tail (HPBT) very-low-drag bullet fired at a nominal muzzle velocity of 2,850ft/s plus or minus 50ft/s (869m/s 15.2m/s).

While environmental factors such as altitude and ambient air temperature affect trajectory, their effect is relatively minor. But probably the most popular bullet weigh is the 180-grain, offering a good balance between flat trajectory, ballistic coefficient and energy to emphatically hunt large-size big game animals such as elk and moose up to considerable distances.

The 180 and 185 grain bullets are also considered the most versatile, with a muzzle velocity of 2950 fps from average factory loads. The 165 grain bullet provides a higher ballistic coefficient than similarly shaped 150 grain bullet while maintaining a very high velocity which is translated into a flatter trajectory. Loaded with 180 grain bullets, the .300 Winchester magnum excels on large body weights, specifically on game weighing between 90 and 320kg (200-700lb).
