I have several rifles I use for shooting only cast bullets. For cast bullet bore cleaning, I've found any solvent works fine, but I generally use Hoppe's #9 or Ed's Red. Even without bore leading, I still run a brush through the bore for enhanced cleaning to remove any powder or carbon fouling that wiping with patches may miss; simply a personal preference that may or may not be essential to some. I try to avoid a completely dry bore upon finishing, preferring to leave just a trace of solvent. A very lightly oiled patch will do the same.
