Crimp

An interesting comment about the .45 ACP by Ross Seyfried in Nosler's reloading book 5th Edition:
"Contrary to popular belief, a slight roll or taper crimp is beneficial, whether or not the bullet has a cannalure. The minimum crimp prevents the top round in the magazine from grabbing the fired case on its way out of the pistol and does not alter headspace."
I've never heard of doing this before and can't see it as a good idea with the round seating on the mouth of the brass, but I'm willing to learn. My routine is to use the Lee FCD to get a .470" taper crimp and I've not had problems with any of my handloads.
My question: Does anyone ever ROLL CRIMP a .45 ACP? If so, what problem were you trying to overcome and did you see any benefits?
