Thanks for the advice thusfar ... it's been very helpful. From what I've heard, my most economical setup is using something like Remington Slugger rifled slugs (~$3/box) with my smooth bore and either a rifled, improved cylinder, or modifed choke. I have both an improved cylinder and modified choke. My next question is, how dramatic is the improvement with a rifled choke tube, versus an I.C. or modified choke? I ask because the cheapest rifled choke I've seen thusfar is around $40, so I'de like to get an idea before I go for it what benefit I would get. Thanks again!
