That's OK Graybeard you are entitled to you opinion. I am just going by my own experience, seeing how I live and have hunted in a shotgun only state. I have tried them with less than stellar results.
Give me a goods smooth bore, and a rifled slug, and I will find one that will shoot semi-accurate. Shotguns with smooth bore's and rifled tubes have very limited range with good accuracy. But if you really want accuracy, GET A RIFLED BARREL.
