Obviously, those wacky Nazis must at all costs retain the enormous military advantage of firearms, against the lower tech inhabitants of various fantastic worlds.

At first, with a small population (at least of TL7 people, though they can quickly come to rule enormous slave farms), this will be tough to do. One way to manufacture firearms cheaply are Sten guns and similar simple designs, which were also adopted by the Germans during the last phases of the war.

On the other hand, it strikes me that before manufacturing new firearms ever becomes a concern, a secure supply of ammunition needs to be ensured.

Which brings me to a question. Does anyone know if there are significant differences in terms of resource requirements or the need for skilled TL7 labour in manufacturing 9x19mm Parabellum ammunition, 7.92x33mm Kurtz or 7.92x57mm Mauser?

As in, does it make sense logistically for them to prefer expending ammunition of one type over another?

Obviously, the less powerful ammunition, particularly the pistol round, will simply not do to replace rifles for some roles, chiefly roles requiring accuracy at a distance. But if the 9x19mm ammunition would be relatively easy to manufacture in comparison with rifle ammunition, perhaps they should endeavour to utilise it (and probably cheap Sten-inspired weapons) for as many self-defence applications as possible.
