The long-awaited, backordered 3-die set of RCBS 8mm Nambu reloading dies arrived today. Ordered 12/27/13, arrived 03/13/14.
There are a few slight differences from the used set I purchased on eBay. Nothing major. The expander die is separate, like my used set. The sizer die does not use the expander 'ball' like RCBS Tech Support sent me. So I'll continue to use my home-made expander die
(I'll be listing this new unused die set in the For Sale sub-forum).
I have three different digital & dial calipers; they all read differently. So, the expander is either .3185", .319", or .321". Take your pick.
This set uses the setscrew locking rings. I really prefer the older split rings. Just my preference.
