Jebs.555 vs indian creek. 555 in a winchester sx3 shooting tss pattern pics ?
That's going to be tight. A SX3 has a backbored barrel. It has a .630 bore opposed to the regular .620 20 gauge bore. I would try something like .570-.585. It doesn't have to be an expensive choke either, I used a .585 Carlson's in my SX3 and it averaged 320/220 patterns with a 1 5/8oz load of TSS 9's.
I shoot Federal TSS #7 with a Carlsons Longbeard XR Choke (.568) out of my SX3. I'm very happy with the results. I will test #9 tss soon. It was on my agenda to test today but some other things came up. Here is a post I put up last year with this choke and load.

Keep us posted on the 9's
Try a Primos TW .570. That choke was too tight for hunting with most handloads for me as well as the old HW7s, but many like crazy tight patterns.
Tested these two rounds yesterday with an SX2/26"/open bead/.585 Carlson's choke at 40-yds.
I'm sure the Kent shells need a different sized choke.
Also, still need to drill/tap receiver to add a red dot.
Through my x3 long beard the Indian creek .555 way to tight at 40, with very lil wiggle room. Now the Truelock .585 has a smashing core and a nice even 20" Pics are on my phone if you want a text. This is with hand loaded 1 5/8os of 9's.
