So if the chokes are .025 and .038 I can assume that they are originally tight-modified and tight-full assuming that the bores have not been opened creating tighter chokes. But could they equally be .015 and .025 and still be Mod. and Full per Foxes original boring? What I'm trying to find out is what is the allowable "range" that Fox might have used in a 16 gauge.

The only constant in life is change.
