Not in my experience
I have found that large pellet loads are not dense enough at 40 yards. More pellets are better, even though they are smaller. The idea is to hit them in the head or neck--- it does not take a lot to fatally damage the brain or spine. Even large pellets to the body won't stop a turkey- the feathers make pretty good body armor vs. shot: When I first started, I used some #2 heavy field loads and and a full choke .............. I hit one hen 5 times and knocked out of the air twice in mile long chase, and still lost her...... I use #6 game loads now, and and extra-full turkey choke. I just aim for the top of the neck now, with much better results.
