http://www.fieldandclays.com/expert_chokes.htm there is some good info on chokes
The Trulock choke chart showing amount of constriction for each choke is applicable to 12 bores only and that is not clear. Small bores require less contriction in thousands of an inch relative to a 12ga to achieve modified, full etc.
nh I am going to test pat dia in 12 gauge at 25 yds what size shot I am going to load up a few rounds all the same same hull same wad same shot size and I am going to weigh the powder on my scale so the reloader won't be able to throw any more or less so the loads are going to be closer than run of the mill shells. I am going to go with rem hulls claybuster wads 8-71/2-6 shot just need to know what size you think for the test and then measure out 25 yds with a tape and put them on cardboard and measure each choke from skeet to xtra full turkey choke. I even have 3 turkey chokes that measure .660 .665 and I think .675 I'd. Will include in my tests what the choke says it is and what it really measures out with set of calipers. Hopefully I can have the test done by this weekend. Weather permitting.
