So far I have simply cut the original cases roughly to size using a tubing cutter, then resized in a 8X60 die and neck turned and trimmed to length using a Forster power case trimmer. I have since obtained an RCBS trim die in 8X57, which I can adjust to the proper length for the 8X60. Such dies come up fairly frequently on eBay and are quite inexpensive.

You PM has not arrived, which is the reason for my lack of response until now.
