All I use s a 20 ga with #6's
Last year I used a SXS Imp and Mod choked 20 ga.
I was really surprised how many fell to the Improved barrel; which fires first.
As explained above, hit them center of pattern and they will go down.
All 30 roosters were pointed and flushed by my dogs. I do not shoot at passing roosters.
Most miss because they are slinging lead at out of range birds. If can see the white ring around the roosters neck it is going down.
