I am out here in CA where slug guns are not very popular. I don't know much about slug guns. I just bought a H&R Ultra Slug hunter and am hoping to shoot it accurately out to 200 yards. We will see when I start shooting it. I plan on shooting top quality slugs like the Light Fields. I would like to ask some of you guys back east what scopes are you using on your shotguns, that have some way to account for the trajectory of slugs, and what is working best for you= dialing a turret, BDC reticle, or mil dot scope.
