I wouldn't recommend gluing a hunting rifle and probably not even a varmint rifle, but when addicted to the search for ultimate accuracy, it's the best system.
Like mentioned above, gluing does give "perfect bedding", but more importantly it results in a "stress-free" action. A properly glued action actually becomes part of the stock with no stresses from screws. Properly pillar-bedded actions can and do shoot well, but even with "proper" torque on action screws there is stress transmitted into the action that isn't present when gluing.
I've never had a "big" caliber glue-in but see no reason for it not to work fine. Can't imagine enough recoil to make an action come unglued. Maybe someone with big caliber experience will comment.
Hope you like your BAT action as much as I like mine.
