I have a new FAIR Iside Tartaruga Gold .410 that came with five screw in choke tubes. Both bores measure .409". I have not had the chance to pattern them yet, but the constrictions measure:
C - -.006"
IC - +.003"
M - +.012"
IM - +.023"
F - +.034"
It will be very interesting to see what they show on the plate.
My Dickinson has tight bores at .399" and .398" with fixed chokes that are ..008" and .008". They have worked very well for me on doves and quail for three years running.
My Yildiz has fixed chokes and bores that measure .400" and .399", and chokes are .011" R and .015" L. It works great on dove and quail, too.
The Verona O/U is bored .410" and .410" and is choked .004" bottom and .011" top. It has worked fine on doves, but never used it on quail.
All pattern well, so the jury is still out for me on what suits me best. Sorry I cannot be much help at this point, but I'm having fun figuring it all out, and killing lots of birds in the process.
