|This was Roy Weatherby's first Weatherby Cartridge, which was and still is a true wildcat
cartridge, as the 220 Weatherby was never produced by an ammunition company.
Unlike the other regular Weatherby cartridges that are produced for sale to the general public,
the 220 Weatherby Rocket is made by altering the shape of a 220 Winchester Swift case to a more
abrupt shoulder neck angle by fire-forming producing over 4,000 feet per second..
It was developed in 1943 and followed by 14 other Weatherby cartridges.
