Hmm, hadn't thought about the goose thing with a rifle before... I shot one with a .243 Win. once, one of my finer rifle shots. Now before you all go ballistic, here's the scenario, and for me, it falls under ethical. We've got dekes in a field next to a small pot hole. A single honker comes in low a silent from the north. We tried to call it in with no success, it lands on the pothole. Unfortunately, it kind of half-crash landed on the pothole and then couldn't swim real well and had it's head down. We figured it was a wounded bird so we went after it. We couldn't get close enough to finish it because it was still swimming faster than we could walk. I went home, got the .243 with my pet 55 gr. varmint load. We'd left it alone for a little while and when we pulled up with the Suburban it had it's head up, swimming perpendicular to me at around 200 yds. I put a little lead on it, aiming for the head, and squeezed. Down went the goose, we picked it up on the north shore. I'd shot it just below the head in the neck, clean kill. We started plucking it, found one wound channel. We breasted it out to investigate, someone had tried to kill it with a .22LR by shooting it in the breast, we recovered the bullet. Legal? No. Ethical? I believe so. We would NOT have done it if we weren't totally convinced the bird was wounded.
