so i'm getting geared up to reload 220-swift and looking back over the history of the cartridge and the 6mm lee navy etc.
the thing i can't figure out is the rationale behind what i'm assuming is a compromise between rimmed and not-rimmed: semi-rimmed
anybody have any insight on why that design was chosen?
