Kroil
Soak it for a few days with Kroil and then clean with either a copper brush or with an all copper Chore Boy pad.
The Kroil will soak in under the lead and loosen it up, making it easier to push out.
Either the copper pads or copper brushes should not have any effect on the barrel.
As Dwalt said Mercury will work and will not harm the barrel.
However its toxic and will harm you, so use caution.
Also I have no idea where or how you would legally dispose of lead mercury mix.
Mercury is not difficult to acquire, if you know where to look. Find a heating and air guy, they usually remove old thermostats when replacing HVAC systems and will usually have some old stats laying around.
There is a bulb of mercury in them, and some have 2 bulbs.
It only takes a little bit of it to work, and 2 or 3 bulbs will supply enough mercury to do what you need to do, and its reusable.
As a life long bullet caster in both pistols and rifles, I have found that the usual cause of leading is poor bullet fit, but there are also other reasons.
I have found that most commercial cast is way too hard, and that leading with occur more often with a bullet that is too hard than one that is too soft.
Also commercial cast and factory cast loads, are often lubed with lube that is too hard as well. If you recover a bullet and there is still lube in the grooves, the lube was too hard and did not do its job.
Lastly, improper cleaning before shooting cast is another reason, though not as common. Shards of copper in the bore, will gather lead, and the problem compounds as more is shot.
I will probably get flamed for the below statement, but here goes....
Once I season a barrel to shoot cast, I very seldom clean it. The lube, fouling will protect the barrel from rust, except in cases, where it is going to set for a long time. I run a patch soaked in Hoppes # 9 and a couple of dry ones, then one with a coat of oil, about every 500 rounds, and that is it.
Lots of luck.

To summarize:
Lewis Lead Remover - check.
Copper Chore Boy strands around a bore brush - check.
Mercury - effective but highly dangerous.
Proper bullets and lube - check.
