Re Reprooving. I don't recall the fee, and its different for different countries. I would have my rifle reprooved by the same proof house that originally prooved it, ie, London or Birmingham in England, Beligian,.... There are firms that do this in the regular course of business. Griffin and Howe are one, and I think JJ at Champlin's too. I think its a couple of hundred bucks per gun all in.

On the shotgun actioned rifles, its my understanding that the actions are hardened differently. But I don't really know.

Editted: PS, I have a pair of English shotguns somewhere between here and London being reprooved. It does take some time.
