I have an old Lyman carbide sizing die that has loaded 1000's of 38 and 357 ammo over the last 30 years. It was beginning to scratch the brass pretty good so I had to buy a new one or "fiX" the old one? I took a 357 brass brush and wrapped it with several strands of "Big 45" cleaning wool. I chucked this up in a hand drill and gave the carbide a good spin for a couple of minutes. I then tested it by sizing some clean 38spl brass and it came out mirror smooth!! I guess the big 45 or brass bristles grabbed the grit and removed it from the carbide ring! Nice when a fix works.
