Is a .670 comp n choke to much restruction for win. 3.5 HV 2oz. #5? Some are saying the overbore mossberg you can over choke. It's shooting #6 ok will kill out to 40 all day just wanted to try #5 but looking for someone that has. should I try the 21/4oz #5. Looking to make the best lead load I can not going to spend $4.00+ for shells when I not going to shoot over 40 anyway. Getting them in close is the challenge.
