Brass wool would more easily show any lead removed.
0000 extra fine steel wool is harmless in the bore, surely, and does a great job of lead removal.
You can scrub a gloss blue exterior gun finish with it and not scratch it.
More like iron wool.
It is also coated with oil to keep it from rusting in the package and thus makes a dandy fire starter, lights easily with a flint and steel, match or Bic.

@pacecars,
I have one of those Navy Arms-Pedersoli Trapdoor carbines in .45-70 Govt also.
22" barrel length, 0.760" diameter at the muzzle, 1.040" breech diameter where it screws into the action.
The .50-70 McNelly Sharps carbine is also 22" long in the barrel, muzzle diameter 0.810", breech diameter of barrel is 1.225".
Both are round barrels.
I think a re-bore is do-able.
Go whole hog and Gemmerize it too ?
