A big cartridge for a big gun, the 300 Weatherby Magnum is one of the famous American custom ammunition maker, Roy Weatherby's designs. Roy Weatherby produced the cartridge in 1944, forming it out of an older 300 Holland and Holland cartridge casing, with the casing extended into the shoulders and the casing taper removed, producing a distinctive 'double radius' shoulder which is pushed far forward and increases the power of the original 300 H&H by giving the gases more room to expand. The size of the cartridge requires the use of a very long action, and this is best paired with a long 26 inch barrel, making the standard size rifle chambered in 300 Weatherby Magnum very large. The 300 Weatherby Magnum is often compared to the 300 Winchester Magnum, although the 300 Weatherby Magnum still develops more speed than the 300 Winchester Magnum. The inert round is fitted with a 30 calibre soft point head. The price is for one round only. Rounds must ship with courier.
