Choke Suggestions for M500 Super bantam

[PAbigbear]

I just picked up a new M500 super bantam, 22" barrel.  I already have a couple boxes of Federal HW#7 to use.  I plan to deep clean the barrel before heading out to pattern with the factory choke.  If I don't get adequate results what is the recommended choke for this setup?  Seems like the carlsons are a relatively good choke that doesn't break the bank.  Thanks!

I have the 500 turkey with the 22" barrel, it came with the x-factor choke (not bad).  I've tried an Undertaker & a Tightwad, of the three, the Tightwad .570 was the best for me (with hevi & lead loads).

Tight wad for the federal heavy weight. I plan on shooting mine this weekend with heavy weight #6. I will post results. Otherwise indian creek .555 with hevi 13 or lead.

My super bantam with the 575 undertaker puts up around 170 in the 10 at 40 yards with fed hwt 7s

I have a 22 inch barreled mossberg 500 and I have had good luck with a carlsons 575

I shot the Primos Tightwad .570 and 3in 1-1/2oz Federal Heavyweight #6 combo this weekend.  It put up 105 hits in a 10in circle at 40yds.
