My regular steel shot gun, ten gauge AYA lightweight in unmodified factory condition. Backup would be a steel barrelled Parker, DH Grade, sleeved to steel and 3 1/2" chambers by Frank Lefever and Son. The AYA has never let me down so the Parker has never killed a duck or goose in my hands. I have not killed a duck or goose with any gun less than a ten gauge for about seven years. I have enough ten gauge ammunition to last my lifetime and more.
