 Lighter bullets of 150-180 grains can be driven to velocities of 3,300-3,500 ft/sec, putting it in the same class as the larger cased .300 Remington Ultra Magnum; Such loads offer a very flat trajectory, making it an optimal choice for deer and elk sized game at very long range.The 8mm Remington Magnum is suitable for hunting almost any game animal on the planet, though certain sub-Saharan Africa countries have a 9.53 mm (.375 in) or 10.2 mm (.40 in) minimum caliber rule for hunting Big Five game - i.e.leopard, lion, cape buffalo, rhinoceros and African elephant.
