I'm thinking hard on getting a 870 20 gauge wingmaster with screw in choke barrel. Do any of you use this as a turkey gun currently? Just wondering if they normally shoot straight or if the point of impact is off from the point of aim. I know my last 870 express shot to the left. I'm not going to any kind of optic, since I like the bead and really like the double beads on wingmasters as they make me put my head down. Thanks for any info!
