Name That Cartridge: Part 11

So I'm visiting my parents this week and my dad was recently given a cartridge collection. There are a LOT of obscure cartridges in the collection. I thought it would be fun to play "Name that cartridge" with the geniuses at Calguns.

Weak sauce guess of 256 newton?

Great guess, that's exactly what it is!

I was hoping someone would go for a 6.5-06

Wikipedia to get a rough idea of the dimensions, and Google images to confirm. A lot of the wiki pages don't have pictures.

Lots of failed calibers to explore. Is there any other resource to find more info on these? I'd love to know what it was that made these fail or miss the conversion to smokeless powder.
