Heavyiron - As i think Ron was trying to tell you, and it really is basically semantics, is that no round is referred to as a Type s.S. 30/40. It could be a type s.S. with a 30/40 primer.
Your aux- St+29 44 round is not likely to be type s.S. at all. I don’t think Polte loaded s.S. ball that late. With no primer seal color, it is very likely a type S.m.E. Lang. The bullet should be a silver-grey color (can range to dark grey). The eej St+ 23 43 round, if it has a silver-grey bullet also, is likely a type S.m.E. with zinc-plated bullet.
Hard to tell with no real bullet description or cartridge picture. Neither round is likely at all to be type s.S. regardless.
the German 7.9 rounds that we would call “tactical ball” types (not including short-range, etc.) included:
Model 1888 (round nose bullet) 226.8 grains
Type S 154 grains
Type s.S. 198 Grains
Type S.m.E. GMCS bullet 178 grains
Type S.m.E. Zinc-plated bullet 178 grains
Type S.m.E. Lang (longer bullet) 185 grains
Nahpatrone (silencer load) Green case and 196.7 grain bullet
The bullet weights in grains are shown after each one.
If you need more help in sorting out the loads, please PM me. I have something that may help you.
