Once upon a time, I owned a 4", 5-shot Charter Arms 44-Spl revolver. I don't remember if they called that model a "Bull Dog" or not but I do remember that it wasn't as common as the 3" versions. At any rate, as it turned out, I never really found a real use for it...The gun itself was too weak to pistol whip someone with, too weak to handle a serious hand-load over the long term, and I always thought that it kicked way-more than it had any right to when used with the relatively weak SAAMI-spec loads which were available back then....Plus, it had a bad habit of shaking both the barrel shroud screw and the little screw in the recoil shield loose. One condition caused the front sight to move around and the other would prevent to cylinder from unlatching......So, I was "one and done" on the Charter Arms thing.
