.280 Remington
From Wikipedia, the free encyclopedia
The .280 Remington, also known as the 7 mm Express Remington, was introduced in 1957 for the Remington model 740, 760, 721 and 725 rifles. The .280 is based on the .30-06 Springfield necked down to accept 7 mm (.284") bullets, with the neck moved forward .050". Having been released 32 years after the.270 Winchester and having no particular advantage over its predecessor, it had somewhat unspectacular sales; Remington renamed the cartridge in 1979, calling it the 7 mm Express. This resulted in people confusing it with the 7 mm Remington Magnum and Remington changed the name back to .280 in 1981.
The .280 Remington is capable of devloping energy nearly equal to the .30-06 Springfield, but with lighter bullets having better ballistic coefficient. Thus, the .280 has a better trajectory and retains more energy downrange. However, the .30-06 will outclass the .280 with bullets heavier than 165 grains. The .280 is suitable for hunting any animal in North America.
Most American rifle and ammunition manufacturers catalogue the .280 Remington. It is not popular in Europe, where it would have to compete with the 7 x 64 Brenneke, to which it is almost ballistically identical.
