I'm shooting a 870 super mag with a hevi 13 choke. I got tired of paying 5 dollars per shell for hevi, so i went to Long beards and my pattern is just OK. So Iv been doing a lot of research on choke tubes and I found Tru Lock or Carlson to be my 2 picks because they made their tubes specifically for the Winchester Long beards. They both compare pretty closely, but I'm Leaning more towards the Tru Lock because they have made a tube designed for each shot size. Winchester® Long Beard™ XR™ #4 Constriction 0.065. Winchester® Long Beard™ XR™ #5 Constriction 0.070. I want to shoot 4's but i'm leaning towards 5's for more pellets. What are your thoughts?
