I can't vouch for the choke, but a good friend of mine takes deer every year, and has for probably over 35 years. Although he's got a pretty fair collection of stuff to choose from, he's most productive with a 20ga (1100 IIRC).
He's got a 1x scope mounted so that he can get a good zero and have a definite aiming point. Before adding that, he'd missed a couple because he was too busy looking at the rack when he should have been looking at the front sight.
