Gary, are you referring the copper "chore boy" that looks like a bunch of copper strands that are all coiled up? If so, I don't see how that can replace the LLR tool. On the other hand IF you're referring to a copper "chore boy" that is a "flat" piece of copper, then that would make sense, but I have been unable to find a product like that in my local grocery store. Also, I have not seen, or heard of, a copper chore boy that is impregnated with soap.
Reason I'm asking all the questions is that I too have a horrendous problem with leading in all of my revolvers and am growing weary of scrubbing, brushing, scrubbing, brushing, and then using the "Lead Away" patches, then starting the process all over again and still not getting all of the lead out.
If you could clarify more precisely what the chore boy looks like, then I could pick one up and get rid of the pesky lead in the bores of my guns.
Thanks.
