Whatever there, Dick. I'm sensing a bit of kennel blindness with you. If you think the Winchester custom shop are the only gunsmiths in the world (oh, & Galazan) who know how to properly choke a shotgun........well, I don't even know how to respond to such statement.
The WS1 choke profile in a M-21 is unique. The point of choke constriction isn't at the muzzle, the barrel is more open at the muzzle. Like Dick, I wouldn't expect anyone other than Galazan's -- as designated Winchester Custom Shop for the M-21 -- to both understand the correct choke profile and be willing and able to correctly duplicate it. If they do the work, it can be recorded as a correctly altered WS1 choke in the Cody records. This isn't important for most people, but Dick's not talking about most people -- he's talking about someone who values factory or Custom Shop authentic M-21 chokes.
