If a race had been held to see which cartridge had become successful the fastest, the 7mm Remington Magnum would probably win hands down. Born of the "magnum mania" of the early 60's, it's popularity has been consistently high virtually since it's introduction in 1962. The cartridge is short enough to be utilized in actions suitable to the .30-06. Remington has often been unable to meet the demand for Model 700's in 7mm Mag, and it is an extremely popular chambering in other makes, almost certain to be found in any action series that handles rounds of magnum-sized width. The cartridge is not for beginners. Factory 150- grain jacketed bullets leave the muzzle at 3110 fps, with 3221 ft-lbs. of energy to recoil with! In ballistic terms, the cartridge is exceptional. To quote the NRA Handloading Manual... "...case capacity and bore diameter seem to represent a very favorable balance between piezometric and thermodynamic efficiency..." Remember to just "throw that out" next weekend at the range.
