Sizing bullets

[Nuclearcricket]

Been thinking about some things over the holiday, I have time on my hands, but I have come up with an idea or 2 but wanted to toss out a question for you all before I get into any of the details.
I know and understand that the preferred thing to do is to shoot bullets as cast, however that isn't always possible as some molds will throw a bullet just a bit too big, ie. a .411 bullet to go through a .408 barrel. What I was wondering is this, if any of you have used the Lee push through sizer, does it leave a raised edge on the base of the bullet and do you feel that the raised edge effects anything adversely?
Thanks in advance.
