7mm Remington Magnum (Handloader issue 344)

 7mm Remington Magnum (Handloader issue 344)
Warning! A Remington 700 chambered in 7mm Remington Magnum with a 26-inch barrel was used to test all loads. Norma cases and Federal 215M primers were used throughout. All loads were assembled using Redding Competition Dies and a Redding T-7 Reloading Press. Reduce powder charges to start loads and work carefully up to maximum. All powder was weighed and dispensed on an RCBS MatchMaster and charge weights were accurate to .04 grain. Velocities are the average of five rounds chronographed at 10 feet using an Oehler Model 35P. Source: Handloader issue #344.
Cartridge History
7mm Remington Magnum (Handloader issue 344)

Remington introduced the 7mm Remington Magnum in 1962, the same year the Model 700 entered the company’s sporting-rifle lineup. The cartridge and rifle became one of the best-known pairings in postwar American hunting. The seven-millimeter bore was already familiar through such names as the 7x57 Mauser, but the new Remington designation gave that bore size a highly visible factory-magnum identity. It quickly became a recurring subject in ammunition catalogs, hunting accounts and specialist rifle magazines.

The cartridge belonged to the belted-magnum tradition that had developed around the Holland & Holland case family. By the 1960s, American manufacturers were adapting that familiar identity to sporting cartridges suited to widely available bolt-action rifles. Remington’s new seven-millimeter offering appeared within that movement. Its history is therefore connected both with older British magnum ancestry and with the expansion of American factory-rifle choices during the middle decades of the twentieth century.

The Model 700 helped give the cartridge a lasting commercial platform. Hunters encountered the pairing in a broad range of sporting settings, and the cartridge’s name became familiar far beyond the audience of custom-rifle enthusiasts. Later competing introductions did not remove it from the literature. Instead, publishers continued to revisit the established Remington chambering alongside newer developments, making its documentary record span many editions, individual rifles and generations of components.

This table is traced to Handloader issue 344, published in June/July 2023. Wolfe Publishing’s contents identify load development on the 7mm Remington Magnum in Jeremiah Polacek’s Reloader’s Press column. The original table notes specify a Remington Model 700 with a 26-inch barrel. That rifle description gives the source a direct connection with the platform associated with the cartridge from its 1962 introduction. The twenty-seven archived entries belong to this particular article context.

The notes also preserve the use of an Oehler Model 35P chronograph and identify the magazine’s testing equipment. Those details mark the record as an individual published account rather than a timeless summary of all 7mm Remington Magnum literature. More than sixty years after the cartridge’s arrival, the article returned to a recognizable Remington pairing through later specialist coverage. Retaining the dated issue link, authorial context and Model 700 barrel description helps locate this table within that long sequence. It preserves one specific chapter in the history of a cartridge whose factory introduction became a lasting part of American sporting-rifle culture.

The pairing of a long-established cartridge with its familiar factory rifle gives this later article a clear historical identity, connecting the original commercial introduction with continued magazine attention decades afterward.
