additionally the carbide dies are called such: Carbide Factory Crimp Die. Available in straight walled handgun calibers only. Rifle dies are just called Factory Crimp Die. No carbide ring since it is being used on a bottleneck or tapered wall cartridge. There is NO crossover on the available production listings although a custom die can be ordered. In other words, if a Carbide Factory Crimp Die (handgun listing) is made for a specific caliber, there will not be a Factory Crimp Die (rifle listing) made in that caliber.
Factory Crimp Dies work on rounds which have powder in place and bullets seated as the final step in the reloading process. They crimp the top edge of the cartridge neck on to the seated bullet.
On top of this there are Lee Collet Dies. Lee Collet Dies are used to crimp the entire neck to about 0.002" under nominal bullet size. they do this by squeezing the casing neck on to a mandrel. The mandrel has to be inside the case neck in order to do this. Therefore there can NOT be a bullet or powder in the casing when performing this step. These are for rifle calibers only. A lot of target shooters swear by this method of neck sizing. I use it prior to neck turning once the case is fully fireformed to my bolt rifle's chamber. Neck sizing should only be performed for a single rifle; ammunition shot in that rifle is reloaded for, and stays with that rifle. It is generally not useful for lever guns, autoloaders, etc.
I agree with everything you said. I probably should have titled the thread. Lee FCD ect for the 44 mag straight walled cartridge! Lee does a bad enough job titling the names of the 4 different crimp only dies in many calibers for most shells available. Another forum people were going into the ramifications of neck sizing vs full length sizing ect ect. On a thread about straight walled 44 mag crimp option!
