Well, choke isn't a big deal, I know that. Like I said, I am a gun owner, 6 of my guns are shotguns. I have shot bird shot rounds and I know how they work too, I know what I'm talking about. If anything, he probably had the choke to spread the shot out since he was quail hunting, thus, making the video even more valid. Doesn't really matter anyway, a birdshot is a bird shot, it is going to spread out; that is what they are meant for.
Please don't try to act like you know guns because you read a howstuffworks article, please.
