A very good hunting pattern but you can do better if you want to.
The Truglo SSX .550 is pretty good choice out of that gun with that load. It's also a pretty inexpensive choke as well. I never could get a tightwad to consistently throw the same pattern out of either of my 870's. The SSX wasn't very consistent either but it threw higher numbers ranging from 120 to 160. The tightwad sometimes would drop below 100, which was a no go for me. The IC chokes were by far the most consistent shooting chokes out of my gun, but they cost quite a bit more as well as the sumtoy's.
