   I forgot to mention last night that, apart from being a rimmed cartridge, .30-30 Winchester has almost the same dimensions as .308 Winchester, the commercial cartridge from which 7.62x51mm NATO was derived. In fact its metric designation, which specifies first the bore diameter and then the length of the empty case in millimeters, is virtually the same: 7.62x51mmR. (If you see a capital R in a metric cartridge name, that means it's rimmed, that is, the cartridge head is of slightly larger diameter than the main body of the case.)

This is interesting to me mainly because it shows that .30-30 was basically an intermediate cartridge before intermediate cartridges were cool. Being rimmed, it's less than ideal for use in autoloaders (rimmed cartridges are susceptible to a phenomenon called rim lock, where the rim of one round in a vertical magazine gets caught on the rim of the one beneath it, which causes feed failures), and since it was designed for tubular magazines it doesn't use the modern pointy bullets, but in most other respects it's very like the military rifle cartridges of a couple generations later: intended to be wieldy in a smaller, shorter, lighter rifle, but still powerful enough to be longer-range and ballistically superior to handgun ammunition. Sub sole nihil novi est...
