To answer your question about "crimp"; use the same amount with lead bullets as with plated.

Actually the term "crimp" is a misnomer when dealing with semi-auto cartridges; the cases are not crimped, as a taper crimp die is just used to remove any flare in the case mouth.

I have been reloading semi-auto ammo for nearly 12 years and have never had the need for a "post seating sizing die". I believe the FCD is a solution looking for a problem as properly adjusted dies will eliminate any chambering issues. Ask the guys that reloaded .45 ACP ammo prior to Lee's FCD...
