So I've got my new HD 870 with the 18.5" barrel and I'll be taking it to my folks who have a bit of land, and I was going to take the opportunity to run a few shells through it - you know, try different loads at different ranges to get familiar with the patterns ... and maybe blow up a watermelon or two for fun. Well my step-dad starts talking about clays and dove hunting, and I'm getting a little fired up, having never hunted before (firearms in general are a new interest to me) and I got to wondering how my short, black shotgun would do in those situations, i.e. if it would behoove me to invest in a 26/28" gun as well. Can y'all tell me if a longer barrel would make hunting or sporting more fun?
