A Lewis Lead Remover will pull the lead in two or three strokes. Maybe 15 if your shooting Ruger. My Rugers were to much of a pain to use lead, but the bore must be smoother in the Smiths because I coukd shoot three times the rounds and remove the lead in five minutes. When I go above 18 Brinell hardness the Smiths rarely get any lead. Those softer waddcutters were a no go in the Rugers.
