teetertotter,They're usually $17.49 at Fleet Farm. Kurly, I remember seeing a thread here somewhere, where a man described exactly what to do. I wouldn't suggest trying it though unless you're a very skilled craftsman and have the right equipment. I'm a former tool and die maker, and hobby gunsmith and have some special stones for that kind of work. It's very simple and easy for me, but I wouldn't trust anyone else to do it. Hey teetertotter, what's a meter?
