Re: Case Prep
Necking up is a pretty straight forward process, and a lot less trouble than necking down. So, you're ahead of the curve on that one. You can usually neck a case up using standard dies, particularly if you use a tapered expander ball. Personally, I prefer the mandrel type expander as sold by Sinclair, and I would imagne some other specialty makers. Better support there, IMHO. Beyond that, once the cases have been necked up, I'd run them through a standard resizing die and proceed with your normal case inspection/prep process as usual. I haven't worked with the Edge, so I don't know just how much fireforming is taking place there. Perhaps someone with a bit more personal time on an Edge might give you some advice here. Beyond that, you shoupld be ready to load as usual from that point.
Check out the Sinclair catalog (available online, too) and you'll see the stuff I've mentioned here. Hope that helps.
