What choke for TSS out of a SA 20?

[wareagle22]

I just picked up a new Mossberg SA 20 and need to find a choke for it.  I'm thinking I need a .570"+ maybe.   Do you guys that shoot TSS use a ported or non ported choke?  Any suggestions will be greatly appreciated.

Which TSS load you going with?  Choke choice depends on the load and what kind of pattern you looking for.    For the 1 5/8oz load of TSS 9's I would see about an IC .562. or an IC .555 if you want it crazy tight.  If you are looking for a more opening hunting pattern, then any cheap .570-.585 choke should do the trick.

I'm gonna be shooting the 1 5/8 oz load.    I'd like a 250/250 balanced hunting pattern but could live with a 300/200.  I'm thinking about a Carlson's .575 non ported and an IC .568 to start with.

Should be good to go!

From all the choke testing I've done with Indian Creek, a .570 gives the closest 250/250 pattern.  The .568 is going to be around 275/240.  My 870 with the IC  .562 shoots 300/230.  That should give you something to start with.  If you really want a shooter, the .555 does 370/200.  You might want a red dot or scope for that one.  Hope this helps.  Good luck!
