Hi
I spent the day putting some automotive cleaner called Sea Foam down the barrel. I now have what appears to be rifling. I've brushed the heck out of the barrel, whenever I quit brushing and run a patch, it comes out black. But after running lead cleaner on the patches it eventually comes out clean. Then when I brush again, I get another totally black patch. I've quit for the night and the whole apartment smells funny, but the Sea Foam stuff doesn't have ammonia at least.
I think I'll take a break and re-size the new Hornady brass I have.
Later
