I just did a pattern check today using that same load in my model 1300 winchester, 1 shot with the Carlson coyote choke tub and 1 shot with the Modified choke, had 14 pellets inside the 10" circle with the Carlson tub and 11 inside the 10" circle with the Winchester Modified choke,the shoots where from 40YDS, I'am using the Carlson tub.
