No worries Dave. Not sure if the end card is still clear as I purchased several cases some time back. But after the info is worn off the cartridges, you can look @ the shot to see about what size is contained therein. If you attend any gatherings where RST is present, you can pick up a few odd boxes and try them.

Another possibility is Gamebore, which has partnered or has been absorbed by Kent(or vice versa) & Gamebore uses that Diamond shot, I believe.

Cheers,
