nocturnal,
I have the same setup as you 835 w/ 24" barrel.
Did you find a choke that patterned well with #4 Buck?
According to the patterning that has been done. We should have good luck with a choke in the .725-.715 range. I'm looking for manufacture with a choke in this range. The problem is all of them do not give you the ID dimensions of their chokes.
I did see the regular Mossberg choke tubes for the guns with regular barrels (not overbored) list a Imp Cyl as .720
Thanks
