.280 Remington / 7mm Express Remington (using Hornady bullets)
Date: Mar 18 2020
The .280 Remington can be traced back to wildcat cartridges (developed around World War II) such as the .285 O.K.H., 7mm-06 Mashburn and 7mm-06, all variations of the .30-06 case necked to 7mm. Remington recognized the potential of this cartridge and in 1957 offered rifles and ammunition commercially. Unfortunately, rather than loading it to 54,000 CUP (the same as vintage .270 Winchester ammunition), it was loaded to 50,000 CUP, which limited performance potential of this cartridge. Nonetheless, it can safely be handloaded to the same pressure levels as the .270 Winchester, which is currently established at 52,000 CUP.
In an effort to increase sales, in 1979 Remington re-named the .280 Remington the 7mm Remington Express without any other changes. This resulted in some confusion with the 7mm Remington Magnum cartridge, and the name was soon changed back to .280; many rifles were so marked and are fully interchangeable.
Among savvy rifleman, the .280 Remington is generally held in high regard. It is an excellent deer cartridge and with premium bullets will cleanly take elk, moose and African plains game while offering comparatively mild recoil. Bullet selection is broad, which technically makes it more versatile than the .270 Winchester with which it competes. Among long-range competitors, wherein extreme shot-to-shot consistency (low extreme velocity spreads) is paramount, the .280 Remington is a proven winner, even winning the 1000-yard Open F-Class in recent years, in spite of competing against much larger cartridges.
In developing the accompanying data, it seemed almost difficult to put together a combination of components that did not perform well. With 139-, 154- and 162-grain Hornady bullets, the company’s most popular weights, Accurate AAC-4350, IMR-4350, IMR-4831 and IMR-7828, Winchester 760, Hodgdon H-4350, H-4831, H-414, Alliant RL-19 and RL-22 powders are top choices.
It should be noted that the .280 Remington case length is 2.540 inches (the same as the .270 Winchester), while the .30-06 is 2.494 inches, or .046 inch shorter. Therefore it is not generally recommended to neck .30-06 cases down to create .280 cases, which are readily available from every major manufacturer.
