It patterns very good. The Jellyhead is a little more open choke, so your not going to get 200 hits in a 10 inch circle at 40 yards. It's more like90 to 120, which is more than enough to kill any turkey. I've been thinking about trying an Indian Creek choke and see how it does, but I'm happy with the Jellyhead. I don't want too tight apattern.
