So I'm taking my son hunting for the first time (dove) and introducing him to firearms. He knows I have them and has shown an interest. I have a private field to dove hunt so it will be a good chance to teach him about safety without any pressure from other people. My question is what would be a better shotgun for him, 20 gauge or the .410? I have never shoot a .410 so I am ignorant on it. I want him to enjoy it out all the pain of a 12 gauge. So any ideas?
