Remington 870 TSS 410 choke question?

[mozer67]

I just got my new 870 TSS Turkey 410 and it came with extended choke marked "full" but can't find any info about the constriction on the choke! Does anyone know what that is on the factory 410 full choke? I was thinking about getting a Jebs or Sumtoy but if this one is adequate I'll pattern with it. Thanks for any input!

Maybe just try that and see how many you get in a 10" circle @ 40 yards, the tss shot does not seem to like a real tight choke. JMO.

Thanks Yote.
