Asked this question before. Since Berry's or Rainier plated bullets have no crimping groove do you use a taper crimp die with them?

With auto rounds I use a taper crimp. With revolver rounds I use a profile (roll) crimp. I set the crimper down until I see the bullet deform slightly at the case mouth, what I would call a medium crimp.
Recovered bullets show a crease in the plating at the crimp, but I've never seen any peeling or cutting.
