In both the U.S. and British scale of chokes, Full choke is the tightest choke for game guns (there are some "extra tight" chokes but these are generally for other thsan game guns). The English 3/4 (three quarter) choke is equivalent to the U.S. "Improved Modified" The English 1/2 (quarter ) choke is equivant to the U.S. "modified" In other words the Mod choke is one half the tightness of a full choke and a the Improved Modified is three quarters the tightness of a full choke.
The Winchester 140 12 gauge has a choke barrel at 28". This is the same choke size as the 20 gauge model.
With standard chokes, Full Choke is the tightest. However, there are non-standard chokes for SOME shotguns (used by turkey hunters) that are Extra Full Choke.
