Today I shot 135 in 10" at 40 Yards at 71 Degrees with Gray Box 3" Win Super X 1 7/8 Ounce #5 Lead through my 870 and Indian Creek .665 choke.
Now, the 20" pattern had some big holes in it, and so it was not to my liking, but the best 10" was Nice.
My INV+ Indian Creek .665 shot great numbers right out of the gate. The same choke in my 870 didn't start out as hot, but over time as I've run more and more turkey loads through it, it seems to be shooting better and better.
