most of the time I use a 22,later in the year I do have to use the 410 or 20 ga.they get skiddish.just go to where you know they feed and set reeeeeeaal still just like deer stand,when you see them start to move.pick several and take one and them go fo the next. when you blast they will hide. if you have picked several you know where they are. look and you can see them laying on a limb.
just go from there. get to another feeding site say 2oo yards away.
