Some of the confusion results from how the different bores used to be measured. Here in the U.S. our military tend to measure from groove to groove, while most European militaries measured land to land. That's how you end up with .303 British (7.7x56r) using a .311 bullet, 7.62x54r and x39 using the...

Full length resizing doesn't return the cases to original factory dimensions. Close, but not quite. Could be your dies are a little on the loose side, or the chamber of your M91 could be a little tight or a combination. If the later, you may need to invest in a set of small base dies to size the cas...

One other thing to consider. It doesn't look to me like the cases were annealed after forming, so the neck/shoulder area more than likely has been work hardened by the forming process. By not relieving the hardening, that area of the case is going to be somewhat brittle, and prone to cracking. I gue...
