Post TEOTWAWKI ballistic wampum manufacture: which calibers?

[Butzbach]

I’ve been scouting to expand my reloading capabilities beyond the calibers I use with an eye toward those which would be desirable for trade (Ballistic Wampum in Jeff Cooper’s parlance) to folks post TEOTWAWKI. My list so far includes: 9 mm, 7.62 x 39, .223 / 5.56 x 45, 30-30, 30-06, .45 ACP, .38/357, .380

What say you?
