Where on the hulls is the chamber too tight? I have seen chambers on some European hammer doubles that were tapered more than USA chamber gauges, resulting in gauge giving much too short indication of chamber length -- I have two such 12s and one 16. I also once had a cheap USA double that had inadequately deep cut for rim on one chamber.

Seems to be tight on the last 1/4" or so as I chamber the shell, like the chamber was tapering down as you went down the bore. It is definitely 65mm chambers. There is a slight wobble , indicating it could stand to be put back on face, and there is slight pitting in the left chamber, but it looks very good all in all.
