Steel Through a Winchester 12

[oneshotkill]

A friend of mine bought a 1937 Winchester Model 12 and is set on using it to duck hunt.  It has a full choke and the fact that it is an older gun worries me.  Do you think that it would be safe to use if he uses smaller size shot?  If so what size do you recomend?  Thanks
