First I shot from about twenty feet through a tight choke at a dot to see if the gun was a straight shooter. It was. I then choked as if bird hunting, backed off to about 25 yards and aimed for the dot. As expected, the patterning was about 60% above the dot and 40% below which means you point so as to see the whole bird over the bead.
If I do that, I can then watch the bird coast out of sight. My eyes work differently, not that what you do is wrong. And it may just be old age on my part. I have to bury the bird with my muzzle, any bird.
