During the early 1940's, engineers at Remington began to develop two 7mm cartridges on the .30-06and the .300 H&H; Magnum cases. Both projects were shelved during World War II and it was not until 1957 that Remington got around to introducing the .280 in the Model 740 autoloading rifle. The .280 Remington is an offspring of the .30-06 with its shoulder angle moved forward to prevent it from being accidentally chambered in a rifle of .270 Winchestercaliber. In 1979, in an attempt to revive their dying cartridge, Remington changed its name to 7mm Remington Express. The name change accomplished little except to confuse shooters. A few years later the cartridge became known as the .280 Remington. The .280 Remington is an excellent choice for hunting all North American game except the big bears. For deer sized game, a 140 grain bullet pushed along with H4350, H414, IMR-4831, or W-760is an excellent choice. For elk and other similar size game, try H4831, IMR-4831or any other powder of similar burning ratebehind a 160 grain spitzer.
