Hey fellas...long time reader...finally decided to sign up. I've just started duck hunting this year (and am totally addicted). I thought the info about shell and shot size on an earlier post was great, but I need some more advice from you experienced guys! Which choke are you using? I've been experimenting with IC and M (both factory chokes). We are hunting over decoys and are only taking shots from about 30 yds and under (90% of time we're waiting until the ducks are very close). Right now I only have the three factory chokes (IC, M, and F). Should I consider getting an aftermarket one? Thanks for all of the advice. It helps us newbies immensely.
