I'd recommend a high quality, plastic coated one-piece steel cleaning rod. As for what somebody said about leaving in some copper, I've come around to that kind of thinking also. Maybe wrong...maybe right, but when I used Boretech Eliminator and took out all the copper from a couple of my rifles, I had to dirty up the barrel to get them shooting the good groups again. Then I used Butch's or Shooters Choice to clean out the carbon/powder fouling and a little of the copper and I was back to shooting great. I was always a 'clean barrel' type guy, but until I discovered Boretech Eliminator, I don't think I ever really had a maximum clean barrel. I just thought I did. So what I've said above is what I'm thinking right now, based on recent experience. I reserve the right to change my mind, and more shooting with a super clean bore might just do that. Maybe the guys on this forum that shoot the tiny competition groups will speak up and tell us what they think about no copper versus a little copper in the barrel. And maybe there is no absolute answer and it all depends on the specific rifle barrel.
