I'm sure everyone has seen their fair share of stubborn guns, but this is my first. I bought a brand new benelli supernova with a 24in. Bbl. I originally tried to pattern it with factory front bead but it shot High with no matter what shelI shot through it. It's is dead on for windage but 12in. high. So I bought some adjustable sights and that got me down 9 more inches but then I ran out of adjustment. I would prefer to use the factory front bead. I am also using 5 different turkey loads in 2-3/4,3,3-1/2 varieties. It shoots the same place Everytime. Could this be my choke tube? I have a primos jelly head. Only ever had this issue with a choke? It can't be the shell at this point because different shells shoot the same. Any input would be greatly appreciated.
