I have never used any solvent which is effective for softening and/or removing lead. The chemical reactions necessary to do this are not user or gun friendly. Mercury will amalgamate lead fouling but is highly regulated by law, highly toxic and fiendishly difficult to clean up if spilled.

The Lewis Lead Remover is the best tool out there for general purpose lead removal. The chore boy works well for the bore but when dealing with the revolver forcing cone, the LLR comes on big time.

The Foul Out will remove the toughest copper and lead fouling through reverse electroplating and is absolutely the best for extremely tough, fouled bores. The down side is that it isn't the most convenient thing to use, so I reserve it for only the worst cases.

As mentioned earlier, Kroil works pretty well on both lead and copper fouling but it is not a solvent. It is a superior penetrating oil which gets under the fouling and loosens it so that it can be brushed away with a bore brush.
