I assume the lee factory crimp die is not to be used with oversized cast boolits?

I might get flamed for this one, but I don't use the Lee FCD for any pistol calibers. It works great for 99% of my rifle caliber stuff, but I'll never use it again for crimping any autoloading pistol stuff. And if you are loading mixed brass, your flare is likely going to be all over the place for each different brand of brass. I would suggest just using your taper crimp die, flare properly, and measure them accordingly. My $.02, and you can keep the change.

I agree with this totally, especially if we're talking about cast bullets in a pistol cartridge. I use a roll crimp for revolvers and I still use my FCD for my blasting .223 ammo but I may abandon it for that, too. I see no positives and only negatives for using it in pistol cartridges, which should use a taper crimp to knock the bell out.

The carbide FCD for semi-auto's is a normal taper crimp.
