Introduced by Remington in 1962 as a short magnum based upon the .375 H&H case this is the most popular and widespread magnum cartridge in the world. The reasons are pretty obvious. Like all the short 7mm magnum cartridges Remington’s version is a very fine all-round big game cartridge being flat shooting and giving a very tolerable recoil. Recoil is a very decisive factor of the shooters degree of success, and the 7mm Remington Magnum delivers about as much as most of us can handle without any practice dealing with it.
None of the short 7mm magnums differs noticeably from the .275 H&H Magnum that appeared 50 years before the 7mm Remington Magnum. The fact that the last one became the most successful is due to the appearance of slow burning powders after WW II and the good and moderately priced rifles made available by Remington with its then new model 700.
The wide variety of bullets available in combination with the excellent ballistic capabilities of the .284” bullets makes the 7mm a good choice for almost all species of game - barring the very largest in Africa.
