I have all lee carbide dies for my pistols. the carbide crimp die is a must have in my book.
It sizes the case with or without a crimp...it will return a flared loaded case back to straight without a crimp.
Hey swamp - you mean a FCD (Factory Crimp Die)? They're great... I use it... but there is a trade off... most semi-auto "failure to feeds" will disappear but barrel leading goes up considerably by nature of design - you're resizing the lead bullet as well as the case... I solved it by going to coated bullets long ago.... I mention this because either one of these issues might be causing someone out there grief and there is workable a solution.... fwiw
