Live round VERY hard to extract?

[81police]

For anybody that was following this thread, I think we found the issue. We tested every AA cartridge we had left. A surprising number of the 120gr. Nosler cartridge OAL measured 2.27+. Some of the 120. Barnes loads measured outside of maximum OAL length as well. This is probably why some rounds stuck in the chamber and others ran fine. I contacted AA about this but they have yet to respond. I would have expected better quality control from them.
