I have heard of a UKicon mummy wrapped rifle slit open JUST enough to lift and open the bolt and muzzle to be proof fired. Then sealed up again. Alas, not cleaned properly - or at all.. Several years later, new owner, opened wrapping with a badly corroded barrel. So make sure you clean it yourself and THEN re-wrap.
