228 WEATHERBY MAGNUM

The 228 Weatherby was never commercially manufactured and information about this cartridge is scarce. On the Weatherby.dk forum it is stated that the 228 was Roy Weatherby’s second development after the 220 Rocket and it was based on a shortened and necked 275 H&H case. In the 12th edition of Cartridges of the World, it is stated that the case did not have the radiused shoulder, but the more conventional one. Roy Weatherby met E.W. Miller in 1940, who was working on the radiused shoulder design in what would become the PMVF cartridge design, so it can be argued that the 228 Weatherby was therefore designed prior to 1940. There is also an article regarding the history of the 228 Weatherby on the IAA Forum
