The 7 mm Remington Short Action Ultra Magnum, often abbreviated as 7 mm Rem. SA Ultra Mag, was developed by Remington in the early 2000s as part of their Ultra Magnum series. It is engineered for use in short-action rifles, offering a powerful performance in a compact form factor. This cartridge is based on a .300 Remington Ultra Magnum case that has been shortened and necked down to accept 7 mm bullets, resulting in a versatile and efficient round suitable for a variety of shooting applications. The technical characteristics of the 7 mm Rem. SA Ultra Mag include a case length of 2.035 inches and a SAAMI maximum pressure of approximately 65,000 PSI. This caliber is designed to accommodate bullet weights ranging from 120 to 175 grains, with the most common bullet weights being in the 140 to 160-grain range which allows for a balance between velocity, ballistic coefficient, and recoil. With muzzle velocities often exceeding 3,000 feet per second, the cartridge offers impressive energy downrange, making it well-suited for medium to large game hunting as well as long-range shooting sports. For reloaders, the 7 mm Rem. SA Ultra Mag offers several advantages. The availability of a broad selection of 7 mm bullets allows for tailored load development to suit specific needs, whether for precision target shooting or hunting specific game species. Additionally, the moderate case size relative to powder requirements allows reloaders to achieve optimal performance without excessive pressure, contributing to barrel longevity and overall firearm maintenance. The combination of high velocity and precision makes this caliber a favorite among long-range shooting enthusiasts and hunters looking for reliable performance in diverse environments.
