Okay, after further research and a few calls I was put in contact with CH4D Tool & Die in Ohio and they manufacture custom and speciality dies. I ordered a set of dies for this caliber at $150 for the set of full length sizing and bullet seating dies. They are one of the few companies that will actually manufacture custom dies using a chamber mold. However, their lead time is now around 24 months but I got lucky in that they normally stock the 8x60 dies for the .318 bullets but they were out of stock last year in May so they entered a production run that should be completed by May of 2020. Yes, I will have to wait but at least I know that I will have the dies when I need them.
As far as cases go, standard 8x60 cases can be resized using the CH4D dies to hold the smaller diameter bullet. The other hard part is obtaining .318" bullets but I was assured by the guy at CH40 that I can easily draw down a .323" bullet using a two step process and so I also ordered two of their bullet sizing dies, one in .320" and then one in .318". For the limited use I am planning for this rifle I think spending a couple of hours resizing the bullets won’t be too much of a big deal.
