Gun used was a Mossberg 835.
Load was 18 nickel-plated #00 from Fiocchi pulldown loads.
I used 38 grs of Blue Dot, 1/2 fiber wad, 18 pellets stacked by 3s, 3.5 Federal hull with federal primer, thick Mylar wrapper on the inside, and BPI original buffer just enough to barely cover the top of the first layer of buckshot. I put a 12 ga overshot card to create a nice crimp.
Havent measured the OD of the buckshot. They are lighter than my cast buckshot.
Heres the specs on the choke tube:
