The choke I settled on for my wife's Mossberg bantam might surprise you....an $18 HS ported Undertaker .582
It throws unbelievably even forgiving patterns.
Consistently 260 in 10" at 40yds with another 240 in the 20".
Perfect for a twitchy bird up close but nothing is going to skirt her either..... It will still dump that 50yrd field bird if needed.
It's been an absolute killing machine.
I should mention though that those numbers are with 1 5/8oz #9 handloads....not the Federals.
