Designed in the 1950's, and also known at various times in its history as the 7mm-06 (a wildcat) and the 7mm Express, the .280 is Remington's answer to the.270 Winchester. Like the .270, the .280 is based on a necked down .30-06 case, with a slightly longer body to prevent it from accidentally being loaded into a.270 Win. chamber.
Remington .280 factory loads are currently offered with three different 140 bullets, all with a muzzle velocity of 3,000 fps and a muzzle energy of 2,797 ft. lb. One is a pointed Core-Lokt, one is a Nosler ballistic tip, and the third is a boat-tail spitzer bullet. Clearly the 140 grain bullet has become the most popular weight for the .280. In addition, there is one load with a 150 grain pointed Core-Lokt bullet at 2,890 fps. The old 165 grain RN bullet at 2,820 fps is also still available.
Reloaders with .280 rifles can take advantage of many different bullet weights and powders. However, they are likely to find that the 130-160 grain bullets are the most useful for big game hunting. Relatively slow burning powders such as IMR 4350, IMR 4831, H4350, H4831, and RL 19 are useful for a wide range of bullet weights in the .280 Remington.
Each box contains 50 once fired brass shell casings. Headstamps are mixed. This is unprocessed brass sourced from commercial shooting ranges. The casings have been washed and polished, but not resized and may still contain the spent primer.
It is recommended that all brass be inspected prior to being reloaded and fired.
