300 Weatherby Magnum History and General Information:
The 300 Weatherby Magnum was introduced to the public in 1948 by Roy Weatherby. The 300 Weatherby Magnum cartridge case itself is nothing more than an improved version of the 300 H&H magnum made by blowing out the full length of the case which then sports a double radius shoulder and a long neck.
The 300 Weatherby Magnum is a very powerful cartridge, loaded with a 220 grain bullet and delivering 2 tons of energy at the muzzle you can safely hunt all of the north american game animals and most african game animals.
The 300 Weatherby Magnum when loaded with 165 - 180 grain boat tail bullets becomes a very effective long range mountain rifle when going after goats and sheep.
The 300 Weatherby Magnum is well known for heavy recoil and will make most average rifleman flinch badly anticipating the recoil, a good idea to keep shooting this rifle accurately is to load down into the 130 grain bullet weight range and do some target practice or varminting as this reduces the recoil tremendously on the 300 Weatherby Magnum.
