I would try a .433 bullet and see if your seater and crimp die will handle it. If so then see if it easily chambers.
My Marlin is happy with a .432 or .433 bullet. Well, as happy as a Marlin 44 mag can be.
 
Nothing wrong with using steel wool in a bore! Those that say it is not good or ruins the rifling......... just prove it to me!
When I build an 18th century rifle I will scrub a fresh cut bore with 3 "OTT" steel wool as tight as I can get it for a minimum of 3 minutes!
And that is usually in 12L14 soft leaded steel! That is Soft Steel
You are not going to even begin to wear a modern barrel with steel wool!

not only that but that slight amount of scratching is actually desirable.
a too smooth barrel doesn't usually do well.
 
My 255gr .433 bullets from Montana Bullet Works came today. Loaded 6 rounds over 8.7 gr Unique. The load was pretty mild, but I put 4 into a cluster at 25 yards, front rest and rear bag of course. The other 2, I shot at bowling pins, 44 mag 255 gr hits the pins much harder than 45 acp. I don't know how to post pictures yet, but I have them Thanks to all of you who aided me in this project, now to shoot the rest of the MBW's up and shop for a mold.

Posting pictures is a breeze. Just below the dialog box where you type click on the link that says "Attach files". A window pops up, select your photos file, double click on the picture you wish to post. Done.
 
or do what I do.
go 'hey take a picture of that and put it in this post', works almost every time.
 
your load is right where my poke little holes in exactly that spot right there with the lever gun load is.
