Fun, fun, fun. I live in grouse country and I've started using my 18.5" tactical barrel with an improved choke to take down those ruffed grouse in tight quarters. I used to use my 870 with a 30" barrel and full choke but if you don't let em get out they're crow burger.
First, the narrator needs to learn to pronounce 'archipelago'. Second, I am again thankful that where I live, north central BC, I drive fifteen minutes from my neighborhood and I'm hunting ruffed grouse. As for killing one of ten flushed, up here it's more like one in three. On a good day it's one in two.
