History:

Remington introduced their new 7mm Remington Magnum cartridge to the public in 1962, this cartidge received great reviews by many as the bullets that could be used carried a very high ballistic profile promising a flat trajectory for long range hunting use in North America. Remington chambered the 7mm Remington Magnum cartridge in their Model 700 bolt action rifle in 1962 and it featured a 1 in 9" rifling twist which easily stabilizes, very long, heavy-weight bullets.

The 7mm Remington Magnum has been chambered by most major high power rifle manufacturers for quite some time and they have offered these rifles with rifling twist rates from 1 in 9" - 1 in 10". Because of the velocity range and quirky nature of .284" diameter bullets in that velocity range, the 7mm Remington Magnum will give varied terminal ballistic performance results with various rifling twist rates.

1 in 9" Twist Rate: 160 - 175 grain bullets, minimum barrel length 26 inches for maximum performance and accuracy.
1 in 9.5" Twist Rate: 140 - 160 grain bullets, minimum barrel length 24 inches for maximum performance and accuracy.
1 in 10" Twist Rate: 115 - 140 grain bullets, minimum barrel length 24 inches for maximum performance and accuracy.

Uses:

 The 7mm Remington Magnum has enough power, due in part to its large case capacity for powder, using 140 grain bullets it will drop deer at 500 yards, using 160 grain bullets it will take elk at 500 yards as well. This is truly an excellent big game cartridge for hunting all of North America's big-game animals. The 7mm Remington Magnum offers one of the best compromises of power, recoil and bullet selections of all high power class of rifles.

 While much has been written about the 7mm Remington magnum cartridge it truly is a great hunting cartridge and is used as such worldwide. In North America 140 grain bullets are used quite successfully for harvesting all deer species, for the largest deer, such as moose, premium ammunition loaded with 160 grain bullets is a very good choice. The 7mm Rem. Mag. offers excellent hunting ballistics when hunting for;
Bobcat - Cougar - Coyote
Antelope - Hogs - Javelina
Blacktail Deer - Mule Deer - Whitetail Deer
Bears - Caribou - Elk - Moose - Sheep.
