Naturally I hear everyone’s theory of what works and what matters, and I hear very clearly what clients want. Second, I am approaching thirty years in the gunsmithing business full time.

I can’t remember who told me the story, but it fits here and explains why I was willing to give this brass sculpting a try. As the story goes Bill was building a rifle stock, took it to a friend to show off his work and to ask for advice.
