It's not so much the length or bullet diameter as it is the rim diameter. You'd have to find a case with a .520" rim diameter. Or very close to that.
The .45-70 is too big(I think turning 88 thou of the rim would be too much.). The .30-30 is too small. So is anything based on it. So's the .303 Brit and .30-40 Krag(that's almost impossible to find anyway).
I suspect you're in a situation where one needs to check the cost and availability of ammo/brass out before buying.
