Tighter Choke for Mossberg SA20 Tactical Turkey?

[BDeal]

I'm using Apex #9's with a Carlson .565 but am also going to try some 8.5 Ninjas. I would like to tighten my pattern up a bit. Does anyone have suggestions for which specific choke to try? Also, will a shotgun typically shoot tighter or more open patterns with bigger shot sizes? I'm wondering if the 8.5's might shoot a little tighter or a little wider out of the same choke compared to the #9's.

Thank You!

I got better patterns for my 9s in my SA 20 when I switched from a Carlson to a Truloc. I don't remember the constriction change though.

IC .555 and .562, tighter choke does not always equal tighter or better patterns.  I shot a .555 IC for years, it bulged or something, IC replaced it and the new choke did not shoot nearly as good!

Currently shooting a Patternmaster code black .565

Started shooting a rob Robert's raptor turkey choke a couple years ago. No going back. Have shot 8.5's and 9's with pretty much identical results

What is the constriction?

I shoot IC .555 with Apex Ninja 8.5 with great results.

In 20 ga using T#9s, I get the best results with .575-.585 constriction

My sa-20 shoots best with the .575 Carlsons. Using Apex #8. Certainly wouldn't want it any tighter as I have to be right on with this set up. Good luck!

To be quite honest I do not know. He only makes one constriction per make/model of gun as far as I know. Sorry I can't give a better answer
