I have tried different brands but not different chokes. Im using an X-full turkey choke that came with my Mossberg. AT 35 yards I have an average of 15 pellets in the head and neck. I always bring my birds in within 40 yards. I was mostly wondering if I should experiment with some other chokes to tighten up the pattern. If this is pretty much the norm I wont waste my money on experimentation. I have just heard so much talk about new loads and chokes that I was wondering how tight of a pattern is the norm these days.
