the 10,75x57 is the rimless version of the 444 marlin. I am sure that nobody by marlin was thinking about this old pre war german hunting cartridge when the 444 was developt but the cases are so similar that the marlin looks like the rimed version. difference is that the marlin shoots 240 -300 grains revolver bullets with 3300 bar max pressure iirc and the 10,75x57 was allways loaded with the same 350 grain bullet like the potent 10,75x68.
I have no data about the pressure of the 10,75 but dare to say it wasn#t more than 2800 bar. in my opinion is the heavy 350 grains bullet the better killer but makes a short to medium range cartridge.
I have not so much time for the 10,75 till now but try 240 and 300 grains bullet, resized from .429 to .424 in the rock chucker just fo seeing how they work

both making 20 cm in soft pine: the 240 grains Remington with 40 grains N 120 explode in pieces but the 300 grains Speer under 40 grains N130 was looking tolerable. its not new that pure revolver bullet in the 444 are only for paper punching. this 300 grains Speer bullet is maybe good enough for small game like roe deer.
