Winchester SX4 20 ga. NWTF

[Oldmason]

Just bought one. Was wondering if anyone uses one and what choke tube. I am planning on shooting Fed TSS #9

 I have the sx4 in 20 gauge with a 26 inch barrel, I bought a .570 constriction from Rob Roberts and it patterns good with #9 TSS , The factory full also has a good pattern so I'd try it before buying one , 20 & 40 yard targets .

570 Should work fine in that set up with TSS.
