Everything except turkey. Not great on turtles though. As a kid the guns I used were pretty basic. There were 2 functional shotguns in the house, a 410 and a 16ga. Both in the 22-24” range. The 16 was IC and depending on what you expected to shoot determined the shells that came along for the ride. It got squirrels to about 80ft easily, running rabbits out to about 30 yards, and dove occasionally if we flushed them. The 16 met its match in the turkey woods, it was a bit too open and I missed at 30 yards so at 16 I worked out a deal on a c-lect-a-choke mossberg 20 ga. And it shot well enough to stop a strut or two. I still have the 20 and I carry it set in between IC and Mod. If it were a 12 with more shot then I certainly would carry it on IC.
The turtle bit... when trying to clear out the predators from a food pond an improved cylinder doesn’t stay tight enough to hit a head reliably at 30 yards.
