I remeasured with a dial Micrometer and they are running right at .477. My son in laws Fired cases measure .471 and My other .280 AI measures .4698-.470. That makes sense with spring back as you pointed out. So it seems to be over sized to me. They look a little pregnant, not good. I will call them tomorrow. To me if its that far off the Saami spec it should be taken care of. I will see what they say. I unfortunately did not figure this out until it was finished. I guess better than never. Shoots good groups but that is only part of the deal. Its a hunting rifle.
