Ithaca Model 37, 12 gauge, usually with a light modified choke tube. I also have my father's mid-60's vintage model 37 with a polychoke on it. If I was shooting for money or my life, that's the one I'd use.
Three shot bolt action mossberg, with a two shot magazine? I'd need to check the model number on the one I gave my son. Most accurate bird gun I've ever used, and longest range. I was knocking down birds after other folks tried twice and gave up.
