Walkalong said:I was thinking the same thing. Maybe he has both though.
Yes, I have Lee FCDs for .45 Colt/.454 Casull (bought two so I don't have to adjust the crimp each time), .357 Mag and .44 Mag. I also have an FCD for .45-70 Govt.

I tried to take some good photos of the split collet's interior crimping ring profile but didn't have much luck. As far as I can tell, the case mouth first encounters a chamfer (maybe 45˚) and then the inside of the collet transitions to a flat where the flats are parallel to the case wall if that makes sense. Both the loads shown above were crimped with Lee FCDs.
