Hello all my friends of NWFA. I have a quick question. My son just hit the ages were he can go on a mentored youth hunt with me. After a long talk with my wife she finally agreed he could go. He wants to start with upland/waterfowl which I hunt every season. I always use a 12 gauge but I know it would be to much for him,so I am looking Ito getting him a .410 or a 20 gauge. I cannot decide as i have never owned a .20 gauge or a .410. Which has less recoil? Which would be a better first hunting shotgun? Which has a better spray pattern? Could the .20 gauge be used for slugs if he decided he wanted to hunt deer with me? Ammo wise i heard the .20 gauge is cheaper. does the .20 have more options as ammo wise? Any opinions/suggestions/advice is much appreciated. Thanks All.
