What bulges are you talking about? The sizer/decapper die takes care of any bulges caused by high pressure and such. Are you referring to the bulge caused by bullet seating?

I love Clays. It is the powder for 45 ACP target ammo. I love Universal Clays. It is the powder for 45 ACP full-power ammo. I will soon buy a keg of each!

What bulge are you referring to? The one created by the bullet entering the case mouth, or the one at the base of the case. You shouldn't have a bulge on the base of the case if you resized the brass correctly. The bulge in the case neck area is normal because the sizer die almost always sizes tighter than factory specs for the brass.

I don't understand why one would need to full-length resize the round once the bullet is seated. The sizing/decapping die does that pretty well. It removes all of the bulge on the base of the cartrige. In my experience, the Lee factory crimp die is too tight, and reduces the diameter of the bullet as it passes through the carbide ring. It then does nothing for the base of the cartrige. If you load a .451" bullet into 45ACP case, the case will expand a bit for a tight hold on the bullet. If you then run this round through a Lee factory crimp die the carbide ring will reduce the diameter of the bullet to .450" as it squeezes the case walls back to their pre-bullet seated condition. This is bad, especially with lead bullets. It is great for reliability, but bad for accuracy and leading.
