My own gun has spent quite a bit of time in the same area, but, not recently. I went 5 for 5 on both woodcock and grouse behind a memorable Gordon Setter one time with my model 17, close to Orr, MN, in the late 1980s.
I've never done that with any other gun in the course of a day.
I only shoot a brace of birds, these days, before I call it quits. I really don't pester the woodcock, either, unless my less than memorable English Setter handles one really well. They really aren't her forté, and I see far fewer of them than I once did.

Good Luck with the old gun.

Best,
Ted
