After measuring the factory chokes the amount of construction seems very light. IC measures .616 Mod is .609 and Full measures .595. The "beginning" of the tubes measure between .629 and .631. Franchi says the barrel specs out at .620 +/-. Given that, my IC has .004 construction. Mod has .011. With the beginning of the chokes near .630 am I getting some jug choke effect?
My new 28" Affinity 3 Sporting measures 0.623" in the bore. You have to measure
before the choke cut in the barrel.
My IC is .615", M is .610", F is .595", So those give me
0.008", 0.013", 0.028" of constriction with the factory extended chokes.
With these chokes they are about 1/2 of a size on the light side of the markings.
