there has been a lot of of talk about 3" vs 3.5" shells and why a particular person choses one or the other, i've seen a lot of blanket statements about how "more payload equals better patterns" and "I only use 3.5" for field hunting" or " 3" patterns better in my 3.5 gun"
does anyone have any concrete numbers on 3" vs 3.5" in their gun for example the hevi 13 3-2-7 vs 3.5-2.25-7's
or the 3" mag blends vs the 3.5" mag blend, any shell will do i just used hevi 13 as an example
i'm not trying to call anyone out I am just interested in the debate and would really appreciate any numbers people post
