I guess, more to the point, I understand that many can't justify the purchase of the .327 from a "what we already have" point of view. (The .357/9mm/.45. etc can already do the job)
My question is, we are alway sold, and buy into stuff we don't really have a need for. We all do it, admit it or not. Commercial enterprise wouldn't exist without our buy in.
What killed the .327, or any other new caliber for that matter?
