7mm mag basics

The 7mm Remington Magnum was released with the Remington Model 700 bolt action rifle in 1962. Based on the then-popular .264 Winchester Magnum, the 7mm Mag's design offered improved cartridge extraction, causing it to usurp the .264 Winchester Magnum's place on the market. Its belted design allowed for more reliable extraction and less chance for catastrophic failure when fired. This is especially desirable when hunting dangerous game that may necessitate a quick follow-up shot.

The 7mm mag is popular for use on the plains of the United States and Africa, where extra range is often required to hunt. The ammo is especially effective and versatile against medium game. There are some detractors to the cartridges belt, mostly hand loaders, but the belt does help thicken the primer pocket area to maximize case life. The Secret Service also uses the cartridges in urban areas for counter-sniper operations.
