I'm looking to pack the 20ga. for turkey this year and was wondering about optimal choke constriction. I see a lot of turkey chokes at .565 but some are as tight as .555 or more open like .580. I'm leaning towards one in the middle, .565, and not worry too much more about it. Right now I'm shooting lead. Any reason to not just roll with the .565? BTW, shotty is a Benelli M2, so Crio choke, if that makes a difference.
