If it's a vintage rifle, likely loss of some value and reduced ability to resell.

With any rifle possible regulation difficulty, this is not predictable.

Mount scope wrong, or mount the rifle wrong when you shoulder it

and get a hit in the eyebrow that will cut you good during recoil. 470's weigh

a good amount usually, scope attached add another 1.25 pounds or so to carry

in the AFRICAN heat for 10 hours a day.
