Following this since I just started acquiring tools and components about 2 months ago including four sets of RCBS dies, only one of which was purchased new. I'm not sure the OP's question has been answered directly.

Also wondering if there's a way to date die sets. Two of mine came from a relative who acquired them used 20 years ago but never took up handloading. I have no idea how old they are so this info has me second guessing them.

I'll edit this; I guess his question about run out was addressed but not the differences in the directions from RCBS. What gives with that?
