[QUOTE="corsair4360, post: 1629347, member: 63474"] Looks more like what I would call an "oversize chamber" that the Hornady brass shows first. My experience is that the magnum chambers ahead of the belt are often larger than the belt by a considerable margin. Technically belted case headspace is set by SAAMI as the belt, with what I would say is generous allowance forward of that. My Browning 338 has minimal expansion ahead of the belt, my brothers 7mm Magnum has more, but much less than my very old Ruger 7mm Mag that after 3 firings the belt could never touch the chamber recess the case had swelled so much.
