I consider the 20 gauge with lead a 35 yard gun. You run across some that are better but it’s the exception not the rule.
I use Win XX 1 5/16 ounce or Longbeard in 5’s or 6’s if I’m shooting lead in a 20.
I’ve killed several turkeys 40 yards with these loads. They are more effective than the paper patterns would indicate.
A lot of ammo is far more effective than paper indicates.
For me turkey hunting is a close range game. A regular full in 20 will easily get a guy to 30 yards. We make things more complicated than needed.
