here's two situations i'm putting out for thought....

1.you and a partner are hunting together. he's hunting doves and you are hunting geese. every now and then you trade shell vests and guns, and switch what you are hunting for. is that legal? it's a grey area.

2. you are hunting doves by yourself about 10 yards from your vehicle. you have a game vest with lead dove loads on you and you are hunting for doves. you see geese off in the distance, return to your vehicle, deposit the lead dove loads and retrieve another shotgun loaded with steel. is that legal? probably, but it would be iffy.
