In a meaningless attempt at statistical significance and consensus
I went through the two threads on chokes. Assuming upland birds west of the Mississippi with a double, the final tally among those willing to say:
7 for IC / IM
7 for Skeet or IC / Mod
Surprising 4 for CF
1 M/IM
1 MF
Some favored spreaders but did not specify choke; assume tight.
I would think by adjusting shot size a guy could do with one gun and an ounce of shot for bobwhite and western quail, prairie grouse, mountain grouse, pheasant, huns, and even chuker with any combination, a good dog, and a bit of self discipline. It's not like we won't eat if we choose not to shoot at birds we don't have confidence that we can cleanly kill and retrieve.
