Shooter's Choice comes in two flavors:
- Original "Shooter's Choice" which is a powder solvent/moderate
copper remover -- not lead
- "Shooter's Choice Lead Remover" which is intended for a similar job on lead deposits -- not copper.
I don't find either all that much to write home about.
If you have a copper problem, get KG-12

If you have a lead problem, get either a Lewis Lead Remover and/or wrap some "Chore Boy" copper pot scrubber (
not the steel core version) around a worn cleaning brush and go at it with some solvent of any kind. Both the Lewis and the Chore Boy
physically scrape the lead out, and do it well
