Tom,
No, they were a for a muzzle-loader without a patch.
I think you got the numbers mixed up but I also understand the memory thing as I do not remember a lot these days myself.
MM 352 (232) and MM 353 (233) have a name problem as they are called Burton after their designer, Harper's Ferry as they were made there, and called a pistol carbine bullet which in my humble opinion is a mis-nomer as they were a musket/rifle bullet/minie.
I hope this helps you out some what.
