Live round VERY hard to extract?

[Variable]

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.

That is long. I've loaded some (120 Nosler BT) that ran out as far as 2.271-2.272ish and got away with it, but I wouldn't load for general use that way. I usually load to 2.267ish these days.

ETA: I wonder if the ogives are a touch different on the bullets in question? That could account for the seating depth variance if no one caught it...
