Currently using a jellyhead in my 20 gauge 870,thinkin of trying a kicks GT.anybody got any experience with these chokes and how they performed(with lead of course).currently getting 120 +/- with remington premier 3" 1 1/4 #6 at 30 yds with the jellyhead just for reference as to what im getting now.just curious if it would be worth the switch.thanks
