I hardly ever use them, but when I do I use a pistol brush, they're softer and you can reverse them if you want to. I think the last ones I got were made by Tipton.
Bob,
No, I have never used the lead remover cloths. However, I used to shoot Federal UMI ammo in a sporter rifle I had and used to use JB in it regularly and centerfire brushes too. The Federal leaded badly.
