I'm sorry, but I point while aligning down the rib, bead or no bead. You COULD call it aiming, but there's no rifle sights to align, just pointing down the rib with a good fitting stock and a cheek weld. I have no problem putting a slug, not shot, a slug on target at 10 feet. It's easier than putting a moving dove inside a 30" circle at 35 yards. I don't know anyone with "sights" on a bird gun. And, if you think it's so danged easy to shoot a moving target, let along a dodging and darting dove at 35 yards, you haven't done it. On a good day, I can be one for two, but I have to concentrate on my swing and follow through to do that. There are days you go out there and just feel stupid. That's when you gotta sit down, figure out what you're doing wrong, and start concentrating.
You cannot "aim" a shotgun with just a bead, anyway. The bead is a reference, that's all. There's no rear sight to put a front sight in, so where's the "aiming"? And, in the dark, I'd rather not have rifle sights on the gun, personally, takes away the instinctive point of the gun and hard to see.
So, anyway, I think this is a battle of semantics. I just don't call shooting a shotgun "aiming" unless it's a slug barrel with rifle sights, necessary on a slug gun for good 100 yard groups. You ain't shootin' at an intruder at 100 yards, though. In MY house, all 1100 sq ft of it, it's practically contact range.
Hell, I've shot 2" groups off the bench with my 12 gauge double shooting foster slugs at 50 yards. There is no semblance of a sight on that gun, just a rib and a bead and I tend to ignore the bead.
