One friend I have said that lengthening the chambers ever so slightly to 2 5/8" will not make the gun out of proof.
Recommend or not recommend?

Is your friend a European trained gunsmith? Is he familiar with English and European proof, did he measure the walls, note the original proof dimensions, account for any honing of the bores, examine the chamber and forcing cone area with magnification, inspect for corrosion under the ribs? Is the gun in proof, now?

Asking for a friend.
