280 Remington History and General Information:

 The 280 Remington is based on the more popular 30/06 cartridge case and very similar to a earlier wildcat cartridge 7mm/06. Remington began producing the .280 Remington in 1957, later changing the name of the cartridge to the 7mm Express Remington in 1979, and still later Remington reintroduced the cartridge in a model 700 rifle and renamed the cartridge to 280 Remington again.

 The 280 Remington cartridge did not catch on in 1957 in the Remington rifle model 742. When the 280 Remington / 7mm Express cartridge was reintroduced in 1979 the one noticeable difference was the advertised velocity increased approximately 100 fps. and this according to Remington was do to the use of slower burning powders that had been developed since the original 280 Remington cartridge was introduced in 1957.

 One of the other quirky extensions of the 280 Remington / 7mm Express cartridge is the Remington rifle model 725 as these rifles do have different rifling twist rates varying from 1 in 9 1/4" twist to 1 in 10" twist.

 The 280 Remington / 7mm Express is a great cartridge and a great alternative to not using a magnum rifle with almost equal ballistics and a little less recoil.
