All right ladies and fellas. Going to try my hand at turkey this spring and I have a couple of questions for ya. First let me say that I will be using a rem 870 express shooting a 3" shell. My first question is what range do I pattern the gun to. And my second question is what type of choke would I use. I know I have to just go out and shoot to find what combo shoots the best pattern, I just need a starting point. Thanks for all the help

Jay
