The 7 mm Remington Magnum rifle cartridge was introduced as a commercially available round in 1962, [2] along with the new Remington Model 700 bolt action rifle. It is a member of the belted magnum family, almost all based on rearranging the case configuration of the venerable .375 H&H Magnum. [citation needed] (Notable exceptions are the Weatherby family of belted magnums, whose double shoulders are unique.)
The 7 mm Remington Magnum offers ballistics superior to the .30-06 Springfield with all equivalent bullet weights, the most popular load being a 160 grain spitzer loaded to 3000 ft/s. This cartridge is capable of taking any game in North America, although one may do well to select a larger caliber for big bears.
On its introduction, the 7mm Rem. Mag. substantially usurped the market share held by the .264 Winchester Magnum, which went into sharp decline in popularity and sales after 1962.[3] Maximum pressure is set by SAAMI at 61,000 PSI.[2]
Remington has recently offered Managed Recoil ammunition for reduced recoil when shooting and less damage when hunting smaller game.
Popular web gun author Chuck Hawks calls the 7mm Rem one of the great all-around rifle cartridges.[4]
