That is an impressive pattern I will have to look into possibly doing a little reloading next season I have accurate scales as I used to do quite a bit of reloading before getting rid of my stuff a few years back and I like you would reuse hulls over and over but if I'm spending 60 dollars for a lb of shot ill splurge for the new hull. I would prob look at the data behind 8s and 7s as well sort of the same argument as 5s vs 7s if I'm going to shoot far I want the KE to go with it.
