With all the new Ammo makers, The new trukey shells out peform, the shells of yester year.
With the extended range of the new shells.
With that said, I do think that a 20 ga will do a good job.
Plus the reduced recoil.
Espeasly if you are older, or have joint problems.
I have had rotator surgery on my right sholder.
So I think 20 ga is a good one.

JMHO
