Walkalong, I can't resist either, especially when I strongly disagree to statements like this;
For reloaders I give you the Lee Factory Crimp Die. In its two variations, it can crimp a case mouth right into a jacketed bullet that has no cannelure whatsoever, and it can essentially size a finished round which means it therefore resizes the bullet inside the case or case neck.
First there are three variations of the lee final crimp die, two for handguns, one for rifles. Second, as Rusty said it only post sizes rounds that are out of spec. Your statement makes it sound like it post sizes every round, that's simply not the case,(no pun intended). As Walkalong said, I too think lee has some quality control problems with the inside diameter of the carbide ring, it MAY be undersized so it WILL post size even normal rounds. If that happens, return it to lee, they'll correct it.
If you make mistakes in your pistol loads and you want to run them through a sizing die to make it so you do not see your mistakes, you can do it with the Lee FCD or you could simply run those pistol round back up your carbide sizing die. Both dies will make any bulges disappear, but neither will correct the original problem, and both will simply swage a bullet that is too small for the barrel. The cartridge will fit, but it won't shoot well.
That's just plain wrong! You make it sound like both dies are the same inside diameter. They're not! The final crimp die's carbide ring is supposed to be the same size as a saami chamber drawing, minimal size to chamber in even a match chamber.
Some say the FCD is simply a mistake eraser. So what mistakes are we talking about? Instead of condemning the FCD as a shortcut to ammo that simply functions, how about explaining the mistakes that lead to bulged rounds that might need such a correction.
I too am tired of all the lee bashing that goes on here and on other forums. I don't know if it's elitism or just what causes it. I'll recommend lee to a new loader every time. It may not have that prestigious name or the polish that the extra money buys, but it'll work and work well. I wonder if it's envy, because Richard Lee has the genius to create things like the FCD, collet neck die, a classic turret? Or the "better than rockchucker" lee classic cast?
