Choke for 20" barrel stoeger

[drakekilla12]

What constriction and brand choke are you guys shooting with beretta/benelli style threads? I assume at the least a .660.

Thanks boys

I have tried everything from 650-670 in my stoeger and so far the sumtoy 650 has been the best. Mine has a 24" barrel though, I posted pics in the pattern thread
