I agree with the others , brass is too hard, I started with plumbing caps filled with lead, an later dedcided to buy some solid copper boppers, I didn,t like them because they were harder than my homemades, went back to making my own, I do think if I stayed with the solid harder ones I would get use to them. Everybody starts out as a newbie so don't worry about it, and the classic is a great place to learn to knap. Lots of really good knappers an small enough to not be overwhelming, Hope to see ya there, I,m usually in the knapping pit at first lite an don't leave until the lighting gets to bad.
About midnite for this ole boy
