I suppose the bottom barrel has to be somewhat low up close so at the farther distances it arrives on target with the line of sight and top barrel. Mine appears to be good on windage too. Your right about the lower impact saving ya. Without a red dot it's so easy to pull your head up shooting a single bead. I bet it does work well! Seems like it'd be a great advantage having a close range barrel and long range barrel. That's the best of both worlds at the flip of a switch. It really cant get any better than that. I'm already thinking about the 20ga model with 26" barrels too. Think it's called a youth model. I'm not sure i will be able to get the 28 to do what I'd like to without the heavy shot, but the 20 no doubt will. Figured you could go with a heavier than lead in a tight choke then a lead and open choke. Is that how yours is set up?
