First observation, its not just the choke, you need to find the best shell/choke combo.
NAILED IT! Yes.
That said, I've had Hevi-shot 13 #5's shoot great in every 20ga I've tried them in. No matter the model of 20ga. I've had some finicky guns/chokes over the years though!
Mag-Blend makes my Benelli look like a slug gun at 20 yards.
