Does anyone know anything about this cartridge, like muzzle energy or velocity or what the rifle looks like, its a odd cartridge that seems to get no credit.

What credit should it get, aren't there standardised rimless cartridges that do same presently.

Both .30-40 rimmed and rimless were developed by Frankford Arsenal during the original Magazine Rifle trials in 1892. US Ordnance decided to go with the rimmed version - and specified it - due to superior extraction with dirty and corroded ammo. The rimless variant fell by the wayside once the US decided to adopt a more powerful rimless cartridge in the .30-03 (forerunner to the .30-06) firing a 220 gr bullet at a (hoped for) 2300 ft/sec. One could argue that the 7.62 NATO would share a lot in common with that .30-40 rimless - very similar case capacity, etc. Interesting alternative history had the rimless been adopted instead of rimmed. Of course - every other country in the world except Germany felt that rimmed was the way to go for a military cartridge.
