depends what you are using the gun for, if like me i use mine for everything i hunt, dove,quail,pheasant, duck,geese, turkey and coyote, plus fun days shootin clays
I have carlsons mid and long range waterfowl chokes, pattern great, but we can only use steel shot here in calif for waterfowl, not sure about kansas
dont use the stock turkey choke as several guys have had them expand and get stuck in the barrel, i have a cheap $20 hs strut undertaker turkey choke that shoots a good pattern to 35 yds, yet to hunt turkey with it but season starts in a couple weeks
the stock ic, i use for clays,quail and close dove, stock mod for longer dove,pheasant and the full for hard chargin coyote with #4 buck, these stock chokes pattern decent thru my m3500, much better than my other fixed choke shottys i have had, they always had holes in the pattern but still killed stuff, aftermarket tubes probably would pattern better but im not that anal to buy aftermarket tubes for every type of hunting i do and im cheap.... :yes:
of course you mileage may vary, after you get the gun clean all the grease off the mag tube and spring and shoot a couple boxes of 3 inch or 3 1/2 to break it in a bit ,then take a bunch of shells you use and start patterning and go from there
Have fun man and post up how your chokes pattern when you can
oh yea, check this while you are cleaning the grease off, luckily mine didn't stick and i didn't have to break it in much, seems like some had this problem some don't but its an easy fix if you do, seems like all the newer ones out now don't have this problem but its worth checking
