I have a digital caller and if you have anything like that, just get into an area where the crows like to roost (night) or feed (morning) and get there early. This may take some scouting. Put that call to work and don't stop it. I use a 12 gauge Remington Wingmaster. Good 7 1/2 or 6 shot, depending on the area. Sometimes I know they will be close, other times I know I will need some more pop. Good luck, any more questions P.M. me. Hope I helped.
