I will jump out on a limb here and say a 410,they are easy to hit cans/clay birds
I have to disagree.
A .410 is a for an expert wingshooter not for a novice. Its ok for plinking pop cans and squirrel hunting for a novice, but not wingshooting. A 20 guage is far far better as a starter shotgun- low in recoil, adequate shot charge, and can even be used for deer hunting.
