actually, it is not a straight walled case
The .30m carbine case has a very slight taper, about .02 from the head to the mouth. I don't know if they still do, but in the old days, they used to recommend lightly lubing the cases, even when using carbide dies.
Lead (cast or swaged) bullets should not be used in the carbine, as fouling can clog the gas port. Jacketed or plated bullets will do better.
