Unfortunately, nobody can tell you what's gonna shoot best in your gun. More than likely both of those chokes are gonna kill a turkey at 40 with a good TSS load. But the only way to tell which choke your gun is gonna like best is to buy a bunch of chokes, and a bunch of shells and put them on paper.
It also depends what you want. Do you want 220 in the 10, or 320? Do you want a hot core or a high number in the 20?
