Back when I started hunting, my shotgun was an Auto 5 Light 12 that weighed a ton and had a vented Polychoke on the barrel. If you’re young and unfamiliar with the Polychoke, it was the shotgun equivalent of those adjustable hose nozzles that let you widen and narrow the spray with a turn of your wrist. I would twirl the choke in and out, setting it for the shot I expected next as I walked the fields. It didn’t really matter, because unbeknownst to me, the Polychoke had been twirled out so far that turning the collet didn’t make any difference. All it ever shot was Cylinder patterns.
