I put a pretty heavy roll crimp on my 44s and 45s. Question is can you have a too heavy of a crimp?
We use a solid carbide insert, ground to a special contour that does not leave the objectional belt mark on the case, common to ordinary carbide dies. With a carbide sizer, no case lube is needed, and you don't even have to clean your cases.
No need for a taper crimp die, plus better accuracy with Lee Dies. Taper crimp dies are used to correct the problems caused by the improper expanding plug design or adjustment. They distort the bullet shank and reduce accuracy. Because the Lee Expander flares the minimum amount, consistent with easy bullet insertion, all of the flare is removed with the bullet seating die, thus eliminating the need for a taper crimp die.

For handgun rounds, can you avoid the crimp all together? I'm looking at the Lee Turret press and it seems that the 4th crimp die is optional, since the expander die doesn't over-flare the case and the flare is eliminated in the bullet seating die stage. I would think that cases would last longer if you don't crimp them.
