We bought Dad a Remington Model 7 for Christmas. It was advertised as a 7mm Ultra Mag, and that's what was stamped on the barrel. We took it out today and encountered a rather amusing problem once we hit the trail we use as a shooting lane.
Pictures with 7mm ultra mag:
Any ideas what it's actually chambered in?
Once the bolt is removed the round fits in the chamber, but the bolt will not close behind it or a regular 7mm Mag and the barrel is apparently still a 7mm barrel.
Eye candy and stamps/markings to follow.
