Thread: Expected spread for a full choked 12 gauge @ 30 meters?

The sights are not out, the gun just does not fit you.
You should imagine the "rear sight" on a shotgun as being your eye. That's why your head needs to be on the same spot on the stock every time. If your head is too low on the stock, the pattern will be lower than your aim point. Vice versa. No doubt you've seen adjustable comb stocks? That's how you adjust gun fit (to a degree) and how you can raise/lower impact points relative to where you're pointing it. Similarly moving the comb left or right will change your head (eye) position and hence move the point of impact left or right.
Once a shotgun fits you, you actually don't need to look at the bead at all. You just look at your target (with both eyes) and point the gun at it. Hand/eye co-ordination does the rest. I took the bead off my skeet gun and shoot way better without it as I'm not tempted to take a peek at it from time-to-time.
