Re: What 20 gauge shells do you recommend?
Please don't take this the wrong way, but be careful how you word things. I can't see a WCO coming to look for you over a baiting a squirrel (technically you did in the eyes of most), but your not going to do yourself any favors with stories like these. There is an incredible amount of help on this site. Most of us did stupid stuff when we were younger, it just wasn't in print for the world to see.
As said above, a 20ga with interchangable chokes is a very versatile hunting arm. You generally can't go wrong with #6 shot & a 2 3/4" shell for small game. Good luck & be safe.
