Eric,
The best lead remover that I've used is WipeOut, I had terrible leading in the bore of a muzzleloader, tried everything that I had, then read on the their web site that WipeOut won't remove lead, but it will break down the alloys in lead. Foamed the bore, left it overnight, next day I was getting flakes of lead on patches, a little brushing and one more overnight and the bore was completely lead free!!
A home brew that I've read of, but never tried, that's supposed to be great for lead fouling is equal parts of 3% hydrogen peroxide and white vinegar poured to fill the bore and left for no more than 15 minutes, then rinsed with hot water and brushed.

We specifically state that Wipe-out does not dissolve lead. Most chemicals that dissolve lead produce a galvanic reaction. This reaction in effect acts like a battery. In most cases it will etch steel ( both stainless and carbon steel). It is for this reason that we don't use chemicals that specifically work on lead.
We use chemicals that will dissolve the other metals ( tin , antimony, zinc, etc.) that are incorporated in most bullet alloys. So we work to destroy the integrity of the bullet alloy, and it begins to come apart in small black flakes. This process takes about 24 to 36 hours.
So while Wipe-Out™ does not dissolve lead , it will degrade the alloy so that it can be pushed out with a tight patch.
