My Dad has a 1909 Argentine that has a badly corroded bore.
He's always talked about "doing something with it", like rebarreling it or having a 'smith sporterize it.
The question I have: is it a candidate to have rebored to 35 Whelen, without having to do any other work? Does the shoulder of the 7.65 Argentine fall "within" the shape of the 35 Whelen dimension? Or would he have to do a complete barrel swap?
I figure there are probably a few of you here that know the answer.
