I tried it when much soaking in Shooter's Choice Lead Remover and brushing failed to remove that last 10% of the lead in the bore.

I cut several 1.5 inch strands, and wrapped it around the brush. Pass it back and forth a few times, and Voila! No more lead.

But you should use the pure copper kind:

The ones in local stores are all "copper-coated steel" for cheapness and I don't trust them in my bores. I had to order the real pure copper stuff online. (The bad drives out the good everywhere).

This stuff works and a few pads ought to last years.

I recommend it.
