280 Remington / History:
Centerfire Rifle Cartridges
Written by: Kim Lockhart, Copyright.

280 Remington / 7mm Express:
  The 280 Remington is based on the more popular 30-06 Springfield cartridge case necked down to accept .284" diameter bullets and very similar to a earlier wildcat cartridge the 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 feet per second, 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 models 700 and 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 7mm magnum rifle with almost equal ballistics and a little less recoil. Many ammunition manufacturers offer some excellent loadings for this cartridge today that are more than capable of handling any game animal that may exist in North America including moose and bears.

 To achieve maximum accuracy from your 280 Remington rifle there are several things you need to do correctly that will help increase your rifles overall accuracy capabilities.
First: Properly mount your riflescope.
Second: Properly break-in your rifle barrel.
Third: Properly sight-in your rifle.
Fourth: Properly clean your rifles bore.
 To accurately calculate ballistics for your rifle with ballistics programs you need to measure your rifles scope mounted height.
