Some better options http://www.lcsmith.org/faq/pheasants.html and this assuming the gun is tight and on face and that the head of the stock has been examined for cracks and repaired and/or glasbedded.
I use B&P MB Classic 1 1/8 oz at 1330 fps in my 1906 Smith, but for almost all rough shooting 'going away' shots on tough Kansas and South Dakota birds. The Italian 4s are quite similar to U.S. 5s.
