I have, and am considering against my better judgement, a rifle with drilled holes in the action.
I know, we all have classics with old scope mount holes in the tops of the rear bridge and/or the top of the front ring.
These holes can be reasonably concealed with filling and stippling etc., but what about holes in the wall - a'la G&H sidemounts? Or, even worse, holes in the side of the front ring?

I have been advised to avoid this situation - unfortunately it is on a Rigby magnum so I have a yearning to resurrect the rifle to its former glory - maybe this is a lost cause?

Is welding out of the question or are there modern techniques which can make this feasable?

No Bouldersmith, I am not ignoring you, but you know how I am about square bridge Mausers...
