A few things:
#1. In a RemChoke .730 bore, I believe the Dead Coyote choke is .675, which would probably correspond to .665-.670 in a Benelli Mobil choke.
#2. I really like my .665 Indian Creek "Turkey" choke, but it isn't designed to throw great patterns with large shot like T's and Buckshot. It would over-choke it. It does great with 5's, 6's, and 7's. I read where a lot of people are shooting buckshot through turkey chokes, and complaining about the patterns. They are badly deforming the pellets by using too much constriction. Please try Extra Full chokes, not Turkey chokes, with Buckshot.
#3. I have found .690 to be great in RemChoke or Invector (Primo's Dead Deer chokes), and .700 in Invector Plus, using 00 Buckshot. I get just as many hits (9-10) in a 10" circle at 35-40 Yards with #4 Buck or 00 Buck, but obviously more pellets in a 20" circle with #4 Buck. These chokes also throw nice, even, dense 30 yard plus patterns with Squirrel and Turkey loads. They are a true "Extra Full" choke, but not a Turkey choke, by definition.
#4. I can't understand why Indian Creek chose such an open exit diameter for their "Predator" choke? I've been scratching my head on that one.
