Remington changed the shooting international forever in 1962 after they delivered their mythical Remington Model 700 rifle along side the modern day 7mm Remington Magnum cartridge. Using 300 Winchester a shortened .375 H&H Magnum case paired with a .284″ bullet, the 7mm Remington Magnum (regularly known as the 7mm Rem Mag, 7mm RM, or 7mm Mag) offered a giant ballistic development over the .30-06.
Indeed, the 7mm Mag will shoot the equal weight bullet faster than the .30-06. Additionally, the smaller diameter .284″ bullets the 7mm Mag uses have a higher ballistic coefficient and more sectional density than .30 caliber bullets of the equal weight used by the .30-06 Springfield. For the ones motives, standard 7mm Rem Mag masses have a flatter trajectory, greater power remaining downrange, and (all different things same) will penetrate better than .30-06 Springfield masses the usage of the equal weight bullets.
And to pinnacle it all off, the brand new 7mm Remington Magnum cartridge match in a widespread duration rifle movement.
With all that during thoughts, it’s no longer unexpected in any respect that the flat capturing and hard hitting 7mm Rem Mag quickly stuck on with hunters and shooters in North America.
