Wheel guns are fun and the .44 Special is no exception. It is in fact a nearly perfect revolver cartridge. The combination of controlability and terminal ballistics make a pleasure to shoot. Then comes the discussion about cartridge sources in a difficult environment. Reloading only goes so far. No military now uses the venerable .44 Special as a standard round. Weapon round capacity and interchangeably are both factors to be considered in today’s environment.
I might point out that the military also went to 9mm over the .45 ACP, which was a very stupid move. Are you advocating that the .45 ACP was a terrible military round and a failure? The military makes mistakes, and not making a .44 special rimless round for autos was one of them, IMO.
