FWIW, my "Jawja" amigo-- as we only see preserve quail here in MI--and our proposed dove season got defeated about 15 years ago--I bought my Utica era Sterly 20 gauge- 28" Bls. DT, EJ from a retired Judge of Probate, he used it for grouse and wood cock.
Just for the heck of it- I "miked out" the chokes-- .007" right barrel (front trigger) and .012" left barrel (rear trigger)-- I agree with all those who replied touting a tighter left barrel, and double triggers- for the smaller upland game birds. I still prefer a 12 bore for pheasant, with the caveat that here, we are most likely talking planted preserve birds-
Sometime when its a tad warmer, I'll take it out to our gun club range and pattern test it on 36" cardboard patterning boards- but IMO-that is a "static" test- how does it pattern on moving targets is the true test- as well as gun fit when swinging through a moving bird--
Happy Turkey Day to you, Jean and all your family--Miss a bob for me, and in memory of Nash Buckingham and Havilah Babcock. RWTF
