Funny, if the No.2 was rimless, the 350 Magnum would be considered an "improved" cartridge by todays standards. Westley Richards also made a version of the 318 with a more abrupt shoulder which, along with this 350, predate anything P.O. Ackley designed. In fact, both existed before Ackley probably even fired a centerfire cartridge!
