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

Ok, I shot a large sheet of cardboard today and the sights are out.
Not too sure why, or how to correct, but basically the pattern is way too low and a bit to the right.
No wonder I've been missing targets! I don't see any damage or bends to the barrel anywhere.
This sheet is slightly more than 1mx1m in size.
Pattern is rather tight and am happy with it.
See photo attached, this was shot at 30m range.
I was aiming for the area circled in red.
The outer fringes of the spread are just reaching it with the odd stray pellet around the board elsewhere.
I shot it a second time aiming a bit higher closer to 3/4 the way to the top and slightly to the left and got more of the pattern over the centre.
