Went through this myself just last season. Installed a Burris FF III on a 20 gauge benelli montefeltro with a sumtoy choke using Federal HW7
Love the gun, love the setup. My son filled his tag on the opening day of youth season. I went out on the following Friday and grabbed his gun. Killed a big one from 40 yards. Hit the call, heard the gobble and he jumped up from a creek. Put the red dot (which is 8 moa by the way) and dropped him. That gun has been one of my best gun purchases.
Good luck in your search.
