I went ahead and did this wondering if it was guilding the lily. What do you guys think?

That's right. Redding neck sizing dies are made to tighter spcs that other brands. There's a good reason for this. Most neck sizers (not collet type) can and will bend the neck a bit out of plumb when the expander button gets dragged through the neck. I have a couple for some of the rounds I load and I remove the decapper/expander stem and set it aside. I use Lyman "M" dies normally used for cast bullets to properly expand the necks to take the bullets. It works for me and does seem to improver accuracy.
