I never had a problem with the Jelly head but to be completely honest, I never had a problem with the remingtong factory extented xx full choke shooting nitro's number 6 in a 3 inch magnum; also have used the remington nitro 2 3/4 inch mags thru the same choke and wouldn't be afraid to shoot at a turkey at 40 yards; it just depends how deep in the wallet you are willing to go;
I fully agree that it's nice to be able to shoot at long distances, but also remember that one can shoot too "tight" of a pattern because not all turkeys are killed at 40 plus yards; I have killed just as many turkeys with 2/34 in mags as I have 3 inch and I would be safe in saying that most of my turkeys, not all, has been killed 25 yards and less; good luck in your search.............rem
