If you are getting 85-89% inside 12" at 40 yards, you have a keeper. That's extraordinary performance. I've shot buckshot all my hunting life. By necessity sometimes, by choice others. I've hunted deer with buckhot in guns with fixed Improved Cylinder chokes to fixed Full chokes, and every manner of interchangable choke tube in between, as well an adjustable choke. 00 buckshot is notoriously hard to get to pattern very well at 40 yards. I'm still looking for a combo that would give me that kind of performance.

In terms of interchangable chokes, I have found that Improved Modified patterns 00 the best in the guns I have. Although I do have a new Trulock buckshot choke that patterns 000 very well at 40 yards. In fact, the Trulock is the only aftermarket buckshot choke I've ever tried that patterns as well as a standard flush Full choke.

Smaller buckshot, like #4, is much easier get to pattern well. I've found that #4 patterns well out of a turkey choke with a .685 constriction.
