Ken, I use and load for an 8 bore. If using plastic cases there are three different Remington Industial cases and each has to be loaded differently. I suppose when you say you have plastic cases on order then these will be re-sized Industrials. Federal, Winchester and CIL all make them as does Fiocchi in Italy. I have loading information for the various ones and have been tested for pressure at the Proof House.
Can you let me know what components you have access to? I use either Hercules/Alliant Blue Dot or Vectan A0, card and felt wads or Italian Gulandi plastic wads, CCI or Winchester primers and mainly Remington, Winchester or Fiocchi cases. Of the Remingtons each can be identified by looking inside; the older type have a sort of grey fibreous base wad, the next have a yellow plastic base wad and the latest are compression formed and all require different data.
