It's been a while since I've patterned anything new but I still have some things in mind I hope to work on in the near future.
I spoke with a couple folks from Pattern Master today. I gave them my scenario and my goals, what I hope to accomplish. I initially inquired about the Anaconda choke tube but they, having spoken with a gentleman just today about a 65 yard coyote kill with their Code Black turkey choke, suggested looking into that.
The exit diameter of that is wider than what I'd consider to be in turkey choke range at .715 but they're saying it could be used with shot sizes 4 buck and smaller including heavier than lead and even FliteControl loads. It is ported but the design of the porting doesn't interfere with that type of load. (I have to add here that in speaking with them, I didn't get that they're fan boys and girls of Hevishot. That goes in the plus column for Pattern Master.) There is another Code Black choke for the UltiMag called Code Black big game. It's essentially a cylinder bore choke without porting (though it looks as if it is ported) but it has internal wad stripping studs and because of which they don't recommend FliteControl loads (or slugs even in standard 12 ga bore dimensions).
They also said that the technology of that choke has changed over the years and where one might have seen 7 pellets of buckshot in a 10" circle some recent years ago, they're seeing more like 17. The tech asked what kind of patterns I've been getting and after I told him, he too sounded less than impressed, sharing my sentiments. What they're saying is that this choke throws extra full patterns to 60 yards. I believe Shooter linked up a photo guide of what those patterns mean at distance both in this thread and in another thread titled understanding shotgun chokes. I'll have to find that.
If I can pull it off, I have 3 chokes I'd like to try. Pattern Master Code Black, Pattern Master Anaconda, and Trulock Predator. I'd like to try each with 3" 41 pellet 4 buck, Hornady Coyote BB, and Winchester VarmintX BB. Standard wad, FliteControl wad, and ShotLock respectively.
The Pattern Master is another one that has little in the way of published patterns available. It would be a risk somewhat though they too have a very liberal return or exchange policy. 30 days to try it out, if it doesn't meet expectations they'll refund or exchange it for something else till I find what I want. (Or anyone for that matter, not just me.)
