It does look like the other caliber suitable would be 6.5X55. It does sound like an interesting caliber. Just wonder about the availability.
Hmm if Justin and Stan looked at it they would have found a date if it was there.They probably have some manufacturing code that can be deciphered ,I had a book that told the codes and dates.
