I have a bunch of rifled slugs for my shotgun, shot a few out of my 18.5" and 28". Could never really judge the accuracy due to having just a bead sight. Not to mention I only really ever shoot clays with the gun. So what kind of accuracy could one expect out of a rifled slug? Would it be enough to put a cheapo red dot on the shotgun just to mess around with? Seeing as how I can't afford a nice set of sights right now.
