Hembrug caliber

[whatguns?]

I'm looking to start loading for a Dutch Hembrug 1894 revolver that I've got and my cartridge books don't show a 9.4mm. Does anyone have the dimensional specs on this cartridge. I cut down the casing from a 30-30 and it's a little sloppy but pretty darn close, nothing a bit of fire forming won't take care of. Bore measures .381". Any help would be appreciated.

30 30 cases. Fire form once there Shortened.
I found 41 Long Colt Heeled bullets worked ex.
Might have to ream the inside of the case mouths abit tho to get the heeled bullets in there as 30 30 brass is thick.
regular HB 41 LC bullets should work to. the Heeled ones just fit and are the right Dia for the Rifleing and chamber throats.

Better fitting cases can be made from .303 Savage, but these cases aren't exactly common or cheap. Given the pressures involved, and the thickness of the cases, .30-30s aren't going to fireform too far back toward their heads. An option for thinning cases, for a better bullet fit, is to expand the case on a tapered mandrel to the correct ID, and turn down the OD while the mandrel is in place. Might be easier than reaming.

Try 41 Magnum cases.
