Well im wondering what choke you guys have had good luck with out of a x3 20ga and the heavyweight 7s?
My Bps likes the hevi choke with the Fed HW 7's. Shot today and you can see the pattern in the 20 gauge pattern thread.
That gun and 562 has the high numbers on our test rang.
I shoot sx3 20 nwtf model with a cantilever barrel, Fast fire 3 scope. My best pattern came from a sumtoy 562.5 choke, averages 180 in a ten inch circle at 40 yards with federal heavyweight 7 shot.
I have NWTF sx3 20ga.
So far I've ran factory extra full
Mad max .560
And puregold .555
The pure gold is what I've stuck with my gun likes the .555 pure gold not tempest. Haven't counted but it's dense and even fast fire 2 on top.
