Wing shooting can be weird. With big game, you typically have the luxury of taking your time and making a well aimed shot. Anatomy + marksmanship = killed big game. I never second guess my archery or rifle set ups because it just doesn't seem all the complicated if you have some discipline in taking only shots you feel good about and sensible equipment you know how to use. When I've messed up I rightly blamed myself.
Upland hunting is different- you gotta make a quick shot, and half the time the bird completely surprises you, even if your dog tells you its coming. Guessing range and lead is on the bird is instinctual. Misses happen. As does wounding/unrecovered birds, unfortunately. When I was starting out, a wounded/unrecovered bird meant "wrong gun/choke/shotshell" in my mind. I often felt I needed more oomph and/or more choke if I didn't kill a bird clean. "If I'd only had my 12 gauge and a full choke I woulda killed that one". I'm certain the "more choke= more pellets on bird= better kill" thinking is wrong- that's only true if your aim is perfect, which is the exception rather than the rule. If your aim is a little bit off with a tighter choke, you may be getting fewer pellets in that bird than a more open choke. Ditto for bigger shells- recoil might mess with your aim (or might not).
I've now settled on one gun/choke combo for upland. I'm not a minimalist- if I felt like changing chokes/gauges would help, I'd do it. (I do adjust shot size for species/wind conditions). But I think a gun that fits, is easy to carry, and you tend to shoot well is more important than the rest. Put some high quality shotshells in there, and don't overthink it beyond that.
