If he gets 'gun shy' about the ammo, he's still in luck because Martini Cadet rifles are pretty sought after. Some guys buy them because they are less common than many other Martinis, so they round out a collection nicely. Others buy them to rebarrel. You see quite a few converted to 357 magnum or 22 Hornet and even converted to rimfire because they are small, lean actions. If he decides he wants to sell it and buy a .303 Martini to shoot he should be able to do that fairly easily. As fast and easy as anything is in the snail's pace world of antiques.
