I just got a set of old english engravers on Ebay. I heard the english steel was superior, so I waited until I could find some. Can you tell me how many hours of practice it takes before you become proficient at engraving. I'm starting to build my own rifle, but fear I won't be able to handle the engraving, yet I want to do it myself. Also, is there some material you can practice on rather than wasting flat brass?
