I have a kick's gobblin thunder right now, but i was wondering if their is a better choke tube that is designed for the heavy shot style loads that will put alot of shot in the head and neck out to 45 plus yards? I am not sure if you can use heavy shot in my gobblin thunder. Give me suggestions on a good tube, shell brand, and shot size that will give me what I am looking for. By the way, my gun is chambered for 3 inch shells. Thanks.

For my 870 I use the Remington Hevi-shot choke Don't know if you can still get it since they dont make hevi-shot anymore heard good things about the Primos JELLYHEAD or the super max hevi-shot by MAD calls

I use an undertaker2 along with 3", #5 federals.
Worked great for me, hit my tom at 20 yds and he never knew what hit him!
When I was sighting in my gun I shot at 25 and 40 yards and kept my pattern in a 14x16 target.
