previous choke was a Jellyhead 660, undertaker 665, and a carlsons 660. i was way to tight and patterns were blown! with the 660 choke and the mag blends 5,6,7 i had 155 in a 10" circle at 35.
with the undertaker 675 choke i used regular lead shot and got an even 155 in a 10" circle at 35 yds.
i may have pulled a bit when i shot to the right! thats why i have some room on the left i bet.
