7mm REMINGTON MAGNUM
7mm REMINGTON MAGNUM
After refusing for years to produce a metric magnum, the pressure in the American market became so great that Remington introduced the 7mm Remington Magnum in 1962 along with the new, improved Model 700 bolt action rifle.

The 7mm Remington is essentially the .338 Winchester case necked down to 7mm. It is a fine long-range, big game cartridge that can also be used for varmint hunting. With a wide variety of bullets available, the handloader can utilize this cartridge for any game in North America and most thin-skinned varieties of African game as well. With bullet weights of 150 grains or less, Accurate 4350 and 3100 propellants are recommended. With bullet weights of 160 grains and heavier, Accurate 8700 is the best choice.
The SAAMI Maximum Average Pressure for the 7mm Remington Magnum is 61,000 P.S.I.
