Federal also changed the primer and propellant to make the shells shoot cleaner. Although the goose hunting around the Twin Cities wasn’t great, I got to shoot a couple of Canadas with the new stuff, too, so there was applied patterning along with the theoretical stuff. It will be available in 10, 12, and 20 gauge loads.
I know, it’s a lot of engineering just to kill a bird, but it works.
