I have and use the Lee factory Crimp die. I haven't really tested different variances in my crimps, but from what I have read both on crimps and on the dies, these give a more consistent crimp than some other dies. Realistically, you don't necessarily need a lot of crimp if you have a bolt, so I stick with a lighter crimp. But depending on the type of bullet you use, you may need to crimp. not much experience here, so someone else can chime in on that.
