I found the sticky
Used search engine and it seem to give me everything but what I'm looking for. I've only dealt with pistols leading and I caught it pretty quick, and it was an easy task using NO. 9, nylon brush and patch.
I have a 30-30 that has leading in the grooves and the above mentioned doesn't seem to be working very well. Searching on the net, the preferred method was to use a chor boy copper strands wrapped around a copper brush using Ed's Red (if I remember correctly).
Is this the best method known or?
If this has been discussed which I'm sure it has, please provide a link.
Thanks in advance.
