7mm Remington Magnum History and General Information.  The 7mm Remington Magnum was developed by remington and introduced to the public in 1962.  The 7mm Remington Magnum has enough power, using 150 grain bullets it will drop deer at 500 yards. Using 160 grain bullets it will take elk at 400 yards. This is truly an excellent big game cartridge.  The 7mm Remington magnum offers one of the best compromises of power, recoil and bullet selections of all high power class of rifles. Its no wonder this cartridge in four decades has become so popular.  The 7mm Remington Magnum has been chambered by most major high power rifle manufacturers for quite some time and they have offered these rifles with rifling twist rates from 1/9-1/10. If you handload for this cartridge the 1/9-1/2 twist rate will give excellent bullet performance from the 139 grain offering by hornady to the 160 grain boattail of speer.  The 7mm remington magnum when loaded with 139 grain bullets recoil is quite minimal and controllable when loaded with 160 grain bullets the recoil increases quite a bit, a good recoil pad fitted to the rifle will tame the recoil before it gets to your shoulder.   7mm Remington Magnum Barrel Specifications.
