10.4 mm

worst case scenario, you can have Rocky Mountain Cartridges make you up some brass, provided it is center fire.
 
ok , experts
any cartridge substitute for an old 10.4 mm pistol round ?
For an Italian Glisenti......

the base diameter of a .44 mag is only .005 or .006" larger than the glisenti. Check your chamber diameters; you may be able to modify 44 mag shells. Possible that your chambers are oversize by a couple thou. You can put a wooden dowel in the case to keep it from collapsing, chuck it in the drill press and use a sharp file to thin the base where the solid web is. Stick to black powder loads and you should have no problems.
