I am so confused! I have not patterned my Mossberg 835 w/ the Federal 3" TSS #9 or the 3 1/2" TSS #7's that I have yet. But please tell me why I hear that a Jebs .665 choke is the trick , while others say to use a more open full choke in the .720. constriction range in the overbored OFM 835 barrel? I have a plethora of factory and aftermarket chokes ranging from a Briley .665; Stardot .676; a ported Primos Jelly Head & MAD 1006 in .690; HS Strut Undertaker and Mossberg Ulti-Full .695; a .695 or .700 Mossberg Extra Full (not sure which); and a Hastings .710. Not to mention a factory Mossberg Full 2 & BB steel and All Lead and a Mossberg Mod 2 & BB steel and All Lead chokes, both I am unaware of constriction size. I am not looking forward to the bruising effects of patterning that 1989/1990 Mossberg 24" non-ported barrel. Anyone have any suggestions on where to start? I am kind of curious on how that Mossberg Full stamped for "2 & BB Steel or All Lead" will shoot.
