7mm Remington Magnum

The 7mm Remington Magnum reached the market in 1962, credited largely to hunting editor and outfitter Les Bowman, who wanted a round with less recoil than the .300 Weatherby Magnum for clients hunting elk-sized game at long range, while offering more retained energy at distance than the .270 Winchester managed with the bullets available at the time. Bowman had used the .275 Holland & Holland Magnum abroad and found it a good compromise, but it was never sold in the United States, so Remington built a belted magnum case along similar lines for the American market instead.

Its arrival reshaped that market almost immediately: the existing .264 Winchester Magnum lost most of its following within a year of the 7mm Remington Magnum’s introduction, and Winchester answered in 1963 with the .300 Winchester Magnum rather than trying to compete directly in 7mm. The two rival magnums that emerged from that exchange, one from each company, have remained the most widely used magnum hunting cartridges in North America ever since.

All dimensional and pressure figures on this page come from C.I.P.’s own published standard and are recorded as verified; SAAMI, the body that governs it as an American commercial round, rates its pressure ceiling somewhat lower under a different test method. Bullet mass and velocity for Hornady’s 162-grain ELD-X Precision Hunter load come from the manufacturer’s own current product page and are likewise verified. Two further bullet weights appear only in a handloading reference (Accurate Powder), whose velocity figures reflect a specific propellant charge rather than the cartridge itself and are not recorded here; only their bullet masses are.
