Ok, so as I understand it, both of these dies are supposed to create what Lee calls a "factory crimp". What is the difference between the "collet" crimp and the "carbide" crimp. I really don't use Lee dies, except in handgun calibers.

Combines the world's most popular carbide three-die set with the Lee Carbide Factory Crimp Die at a great price. No other die set at any price will produce more reliable or accurate ammo. By separating the seating and crimping operation, you will benefit by a greatly simplified adjustment.

If you shoot plated bullets, before loading any significant amount, do an accuracy test. The Lee carbide crimp die has a sizer ring in it and may resize plated projos. It does not resize FMJs in my experience.
I loaded a small pile of 10mm plated and at 25m half missed a silhouette target and those that hit keyholed.
I did a more controlled test later, different brand of plated, both 9mm and 10mm. The Lee FCD generally tightened up the groups with FMJ/jacketed projos vs non-crimped. The plated generally had a larger group when the Lee FCD was used vs non-crimped.
