Simple answer...yes, the last two patterns are good enough to kill turkeys. Take Adrian's advice to heart and don't try for a long shot with a 20ga. Keep your shots to 40yds or less, and you'll kill turkeys with your Charles Daly just fine.

With the right choke and load, you might, I stress might, be able to stretch your shots out to 50yds, but that is a long poke with a 20ga.
