Awesome 58. I'm looking for one now. A guy I work with builds his own guns and he said he is doing one now with an antique finish. He takes the barrel and plugs it up and soaks it in bleach and apparently it makes the barrel look like it's been through hell and back then he browns it. He is helping me find a 58 barrel in 1:48 twist in which I want to shoot a 600 gr conical I saw on the net. I did find a 1:28 twist custom barrel but I thought that was too extreme.
