I think you ought to concider what they used in the old days: brass shells. A .662 ball fits snugly into a 20 gauge brass shell. Slugs of modern days are made to fit in a plastic shell (with thicker walls), maybe even a shot cup and least but not last they are made small enough to pass the choke of a shotgun without dangerous pressure.

Do you think this undersized slug would expand
enough with a charge of 60-70 grs FFg to fill the barrel's groove successfully?

I wouldn't count on it, maybe you'd be better off throwing rocks...
Here's a clip of my first shots with it...
