I'm in my 70th year and still enjoy the "hunt". I got my first springer in 1944 and my current 4 year old is a wonderful dog.
For grouse and woodcock I switch from a Darne 20 to a Wm. Evans SLE 2 1/2" 12, depending on weather and conditions. When hunting pheasant my favorite is a 12 bore Greener. When shooting doves and skeet I use a Beretta sxs with choke tubes.
