If the pattern was good at 50 yards, which is hard to believe, I would look into a red dot, conventional scope or adjustable sights, to get the gun to shoot where you are aiming. I don't know if there is another choke out there that will pattern at 50 yards. I have shot the Jellyhead with #6 Winchester Hi-Velocitys' and the pattern fell off after 30 yards. Good luck.
