I think some of these questions relate to the possibility that what goes on in the gun before it gets to the choke determines a degree of the tightness of the pattern.

I think damage to the shot due to ignition, forcing cone damage, and/or barrel scrub possibly may factor into choke effect.

Someone mentioned the fact that it was commonly believed by earlier generations that a short chamber increased the tightness of patterns in trap guns. I think that is largely disputed, but the owners of those guns were not easily convinced. How do you feel about that?

I suppose that some mismatch between chamber/forcing cone and ammo could have led to this belief. Rather, I'd guess that some very good shot had a short chambered gun and his competitors needed to blame his success on something. I'd seriously doubt there is data (the real thing) to back this up.
