RE: I finally took the plunge into reloading...what do you think?
DR, That's a good question. I usually use a spray, I use Hornady, when I'm just neck sizing, and at the correct angle I get the inside of the neck just fine. When I use IDW for FL sizing or neck reduction, I use a mica system I got from Midway, I think. A case neck brush by itself will usually get the neck slick enough to pass the expander without difficulty, but have the mica handy if it seems to be sticky.
