Just in case you aren't confused yet, here's some more trivia. Cartridges
such as 44/40 and 45/70 come from the old black powder days. The second
part after the slash denotes how much powder was inside the casing and that
gives you the size of the casing. It sometimes helps to know the history of
the round.

Thanks to all for the answer. I'm assuming the larger x number, the longer
the
case and the longer the case the greater the load of powder?
