For Sale Briley Thin Wall chokes, 1 X-Full, 1 Full, 1 Light Full, 1 Imp. Mod., 1 Mod. Not looking to separate set. $125 FIRM. Posting these for Dad. Almost forgot hese are SERIES 2 chokes, for .735 bore. PM's interest.
The way choke tubes work is simple the key is the bottom of the choke mouth being larger than the bore so as the shot comes down the bore 732/733/735 it jumps into the 740 ID of the choke mouth and then the choke constricts to what you need F/M/IM /LM / IC /CYL. If the bore is 732 then the choke will be tighter by 3 thousands. Briley uses different series depending on Bore size my 723 bore uses S1 series and my 735 bore gets S2 series and they have more for different bore size barrels.
