Leading

[Melnic]

cut some of this off and wrap around a brush is what it took to get rid of the leading I experienced with the HiTek bullets on one barrel.
At its worse, it built up and killed the accuracy in less than 10 rounds.

flakes came out and I put under microscope at work and could see it was lead

I use medium bronze wool wrapped around a brush.

Not sure if one is better than the other. It's still a chore to get it all off.

The Lewis Lead Remover requires a single pull through the barrel. Maybe 2 if the leading is real bad. No pains in any asses required. Just a little muscle.

I have owned Lewis lead removers from when Lewis sold them in the American Rifleman magazine. Brownells bought him out maybe 30 years ago. It is a good tool once you learn how to shape the screen on the mandrel prior to pulling it through. To new users, it can be frustrating if they try to pull the disk of brass through the bore without shaping it first.

^^^ Yeah, nice little cookie cutter hole in the bronze patch. Only took a time or two to get that right. I have done also by having the expandable jag a little too tight. Otherwise, I used the same bronze patches many times.
