Hi, in that case I'd just open the chokes to a tighter Skeet/light IC (.007) in the right bbl and Lt Mod (.015) in the left. For the kind of hunting your doing I'd forget the tubes.
Good Luck!

Agree with Greg if you're talking pen-raised pheasants. Why not both the same with a nonselective trigger? IC is certainly tight enough for released birds, but if you miss with the first barrel, you're going to have a longer shot with the 2nd. But you don't need the left barrel to be a lot tighter, which is why I like Greg's choice. That's very close to the way I would set up a gun for pheasants, and in my case I'm talking wild birds over pointing dogs. But for wild bird hunting, I think double triggers, so you can select instantly, make good sense. Not as important with planted birds, where you're less likely to have birds flushing farther out.
