Those of you who read this little blog know that I'm a fan of the .44 Special. I was over at this forum, discussing the .44 Special and Uncle Nick sent me to the SAAMI drawings of both the .44 Special and the .44 Magnum and pointed out something that I had never noticed.
According to the SAAMI drawings of both cartridges, the loaded maximum length of the .44 Magnum cartridge is 1.610 inches, while according to the drawing for the .44 Special, the maximum length of that cartridge is 1.615 inches. The Special is longer than the Magnum by 0.005 inches. That's interesting, because the Special case is shorter than the Magnum case by 0.125" (1.285-1.160). That's interesting because the Special case is shorter, but the maximum allowable COAL is longer.
I had never looked at the drawings side by side and compared them. This brings all sorts of questions to my mind, and I'm going to have to ponder on this for a while. Is it possible that there's more powder space under a Special cartridge than there is a Magnum cartridge?
