Know what your pattern is doing before ever hunting with it. Use the 870 till you have found a load and choke that works for the 835. I recommend forgetting FCW in the 835, they were horrible for me too. Hevi 6 or 7 or for lead Longbeard 6. They will work with the Jelly Head. If you are wanting super tight patterns, find an Indian Creek .675 with wad catchers.
