this was a great find fuhrmann!
ok, the 24 ga here used was a very ligth load. 15,1mm long, 21,9 gramm cats head with 2,5 gramm (38,5 grain!!!!!)rifle blackpowder. the ballistic is what we think, only 342 m/sec

the 24 ga RWS cats head was 18,70mm long, weight 33,3gramm. obviously that there are different weight's around:

....
I have here camber cast's from 3 different guns

28/50 cartridge, Husqvarna Mod 17 A

24/40 cape gun, Funk /Suhl

20/40 heavy target rifle with Mauser M 71 action

all have a mark at 40mm to show the end of the case in the chamber. the husqvarna have a chamber for a 50mm long case and the 20 bore have a lot of freebore till rifling starts. the rifling in the Funk 24 ga starts immediate when the case ends. its clear that you can only load a cartridge with a bullet completely in the case. you get more than 38,5 grains in the case. I think that there is enough place for 70 grain BP in such a combination.( like the 577 snyder! a cartridge that take all game in its time including elephant in india) this funk cape gun is a very light one, maybe it was only build for light roe deer loads.

Lancaster,
you read the wrong line here - velocity for the 24 ga. is given as 265 m/s. This really appears as a "sqib load"; maybe this was untypically low.
The 1877 book of A. Zimmer recommends loads of 3 to 3.5 grams (ca. 46-54 grains).
If there is more volume in the Lancaster cases that you know so well, then this will most probably have been used for powder. Or was it usual to have some wad between powder and bullet, reducing the usable volume?
