some people are encountering problems with the 7's in 3.5 and 3", my 3" new lot shot very well for me,
its hard to compare apples to apples because there are so many variables that come into play when patterning a turkey gun,
things such as barrel cleanliness, choke cleanlinees, temperature, wind, humidity, manufactures shell tolerances, even things such as how hot the shell is can effect patterns, i've shot two identical shells, one that sat out in 80 degree sun for 1 hr and another that was in the cool trunk and the one heated up drastically outperformed the cold one
unless a person is shooting the under the same EXACT conditions as they were last year you are comparing apples to oranges not apples to apples
