So I just started shooting trap for my high school trap team. I'm using a Mossberg 500 with a 28" barrel, and the shells we're using are 2 3/4 7 Shot. I've been using a full choke in it for the past 2 weeks, and I've been shooting pretty well. My team mates are using all sorts of chokes, and I want to try a modified choke, but I don't know if it's a good idea. Ideas or advice?
