I'm looking for options to get .004" tension for a 6mmAR project. I have redding dies for it, but from what I gather, the factory expander won't give me the ~.004-.005 neck tension I'm looking for to run it out of my gasser. I see Widden makes an expander ball kit, but there's not much info on their site.
What's the material? Are they floating? Do they fit redding dies?
Anyone make a mandrel in that size?
Thanks for any help
