Thanks for your response.

I'm out of the duck hunting now. Haven't hunted them since non toxic became the law.(except for a single hunt about 5 years ago) Have never hunted geese. I still have an interest in shot shells and reloading. 12ga is my all around gun and although it has a three inch chamber I've only purchased one box of three inch shells and that was for turkeys.

For your interest, Dad called the decoyed ducks in and landed them. No one was allowed to shoot until the ducks were flushed.
