Someone over at cast bullets is starting a campaign to get Lee to make a FCD with out the carbide ring. At first he wanted a Lead Friendly FCD but it appears John Lee nixed that idea. Anyway. Supposedly the FCD has a special type of design for the crimper. I have read that for years. Anyway, Lee is basically saying what I have said for the last 4 years. FCD is sized .001-.002" smaller then sammi spec. I always thought it was .003" because that is what all mine actually measure at. To be fair it's really hard to measure a I.D. to .001" anyway with regular calipers. He also confirms the "spring back" that I have talked about for years. Basically, Na Na Na Na Na. For the record once again. Use one if you like. I could care less. To each his own. But I was right. The FCD is sized smaller then Sammi spec. Just like I have said all along. http://castboolits.gunloads.com/showthread.php?t=130334 Wanna kill these ads? We can help!
