What is dimensionally close to a 444 Marlin?

I'm playing Doc Jones (Back to the Future) and trying to find a closer fit for an obsolete European loading.
Using 44 magnum brass now and it sort of works.
The bore is .429 so 44 magnum casts work like a dream.
The brass will fireform to the cylinder at which is much larger which makes the loaded rds look like Coke bottles.
Upon leaving the cartridge the bullet (pure lead ahead of FFg BP) begins to expand to the cylinder diameter ( about .454 on average) and shaves off a ring upon encountering the .429 bbl.
Which then greatly deceases the revolver wanting to function til the lead is cleared.
I'm hoping that a 444 marlin (or a reasonably close sized cartridge) cut to a hair under full length will help stop the slug expanding on the jump from brass to bbl. That and the 444 Marlin is a tad larger at the base so trimmed it's going to fit the cylinder better.
Realizing of course that this question will make most diligent reloaders scratch their head and shrug...but it is an enigma.
I'll get a really neat antique back in the game if I can figure it out though
It's a tad longer and larger dia than the Reichsrevolver loading ( which 44 Russian fits like a dream)
Any help would be greatly appreciated.

A Belgian revolver can be in a horde of calibres and the size of the brass means very little. Slug the barrel. Sounds like it might be one of the 11 mm cartridges.
Anyway, the .444 Marlin is rimmless. The only thing it has in common with the .44 mag is the bullet diameter. Nothing whatever in common with the .303 Brit. It's rim is 10 thou bigger for one.

The 444 is rimless? That's news to me...........Sunray still batting 1000........wrong.

You might take a look at 405 Win brass, OP, it has a base dia of .461 or the 9.3X74R which has a base dia of .465 or the 7X57R with a base dia of .470. You can always turn the rims smaller if need be, that's real easy. Is this a bottle neck case like a 44-40? The nominal base dia for the 444 is .470 so it should work like a charm in the 472-3 chamber you have described. You say you may have to trim the base dia of the 444 but then you say your fireformed case measures .472-3, I'm at a loss to understand the thinking here when the 444 is .470 by spec.
