Does anyone know the max case length (not ovearall length of the round), and the trim-to length for the 7.5X55 Swiss case? I wanna take my K 31 out to play and have to make up some food for it first.

Ammo Encyclopedia (3rd Ed.) has the case length at 2.189".
I assume that is max and you would trim .01" off that.
FWIW Cartridges Of The World (4th Ed.) has some reloading info.
Frank also mentions you can form cases from 284 Win.
P.O. Ackley has a little reloading info in his handbook (vol. 1)
Now just to complicate matters, Hornady (3rd Ed.) has a chapter for the 7.5 Schmidt Rubin
which they also call the 7.5 Swiss but is listed as having a length of only 2.140.
I assume that's not quite the same cartridge.

The Hornady Handbook of 1967 shows the case length for the 7.5 Swiss ( 7.5 Schmidt-Rubin) which should be the same round, as 2.140 inch. They list both names on the drawing.
Once fired nny brass cases measure from 2.175 all the way to 2.180 inches. They average 1.1775, but no two are identical.
The once fired and resized cases , LAC stamp, measure a consistent 2.19 inch ....that's strange.
I don't have any new unfired cases to measure, just once fired and fired and resized.
Now I'm confused...2.185 sounds about right!
Good luck
