Yes, the RCBS dies are pricey, but the Reddings are a few bucks more. You just have to wait for the dies.
When I was researching this out for myself, I even called and spoke with Lonnie Hummel at Hornady and he said the same thing as Redding, 6-9 months at first, the second time I called the wait went to 9-12 months, He told me that the demand for reloading equipment was out pacing their ability to produce......
Hornady also requires 3 fired cases as they EDM machiene (sp?) the dies. That's kinda putting the cart before the horse.... I know the dies are good, but I didn't want to wait for dies. And let the rifle sit while I waited. I still would like to have a competition seating die, but that will have to wait. I'm kinda poor right now......
later,
