Quote:The current 7.62X51 magazine is not strictly a single stack as implied by your math.No, it isn't. It's a staggered, double-stack mag. But, each stack has the cartridges lying atop one another, so the height of each 10-rd stack is 10 times the 0.473" cartridge case diameter. The drawing below shows how the rounds are stacked.
(Disregard the position of the top round. The drawing is of a double-column, single-feed mag, whereas military rifle mags are of the double-column, double-feed type.)

Quote:Changing the cartridge diameter changes the available number of cartridges in a non-linear fashion.Not true. See above.
