For one thing, don't worry about what everybody elses patterns look like. You don't have to have 200 hits in a 10 inch circle at 40 yards to kill a turkey.I have never put 200 in a 10 inch circle inmy life, and I have killed plenty of turkeys. The 870 can be a tough one to pattern. With a Jellyhead at 40 yards, I normallyput anywhere from 80 to 120 in a 10 inch circle. That is plenty enough to kill a turkey at 20,30,40, or even 50 yards. Different shells are going to give you different patterns. The best patterns with the Jellyhead came from the Rem. Wingmaster HD. Just remember, the Jellyhead is a little more open choke than some of the others, so you are going to have a little wider pattern. That can be more forgiving at 25 yards and closer.
The stock choke that Remington callstheir turkey choke is .025" more open than the Jellyhead, i'm sure the patterns won't be as open as I have now. I just picked the Jellyhead because it seems to get good reviews for the money but I haven't bought one yet and I'm open to suggestions.
