This thing has really taken on a life of it's own, hasn't it? It speaks well of the depth and breadth of knowledge and experience here. Two schools of thought are well represented here; the target shooters and the hunters, as well as the folks that do lots of both. My only mild disappointment is that the core of my question really hasn't been addressed: can you change choke effectively by cutting a barrel back? There may not be an answer, as the best answers I've heard so-far were essentially "maybe". I now see why polychokes were so-popular in the 50s and 60s. That in itself might be an answer, as they only "constricted" the shot charge for a very short distance before leaving the muzzle.
