CHOKES AS ANY OTHER PRECISION-MACHINED ITEM FOR QUALITY PURPOSES ARE TO BE HELD TO SPECIFIC TOLERANCES--AS I STATED IN MY FIRST POSTING, BOTH THE MODIFIED AND IC CHOKES ARE RIGHT ON THE MONEY WHEREAS THE FULL TUBE IS OFF IN PLACES AS MUCH AS .020--HAS ANYONE CHECKED THE BORE OF THEIR FULL TUBES. I WOULD LIKE TO KNOW IF THE SIZE OF MY FULL TUBE IS SPURRIOUS OR COMMON FOR ALL BENELLI FACTORY FULL CHOKES--

I CHECKED A CHOKE SIZE CHART ON CARLTON CHOKE'S WEBPAGE: THE TUBE IN QUESTION IS MARKED FULL, BUT THE DIAL CALIPER READINGS ARE ALL OVER THE PLACE FROM .675 TO .685. THE CHART PROVIDES A SETTING OF .695 FOR FULL CHOKE. I AM TRYING TO FIGURE OUT IF THE STOCKED BENELLI CHOKE I HAVE WITH THESE LOOSE TOLERENCES IS JUST AN ODDBALL CHOKE OR IF IT IS NORMAL.

I AM CHECKING OUT TURKEY CHOKES FOR MY NOVA AND MIKED THE CHOKES I RECEIVED WITH THE GUN: BOTH THE MODIFIED AND THE IMPROVED CYLINDAR WERE WITHIN CLOSE RANGE OF THE BENELLI CHOKE SIZES FOR THESE TWO CHOKES, BUT THE FULL TUBE MIKED OUT AT .675--.685 (X FULL TO TURKEY ). ACCORDING TO THE CHART I HAVE FOUND ON THESE CHOKES, THE FULL SHOULD MIKE OUT AT .695--IS THIS UNUSUAL--CAN ANYONE SHED ANY LIGHT ON THIS--
