I use a 20ga Beretta, with Rem. Heavy Dove #6's, out of an improved cylinder. I rarely pass shoot, but always hunt with 12-24 decoys and an e-caller. I have a half dozen flocked decoys in my spread, but haven't seen incoming crows favor that side of the spread. My other decoys are mostly Flambeaus with a few Carrylites. Many of the crows I shoot are coming in to the speaker, not the decoys.
