[quote=curioushooter].............................It just dawned on me that J. D. Jones pretty much did the reverse of the JDJ series?with the Whisper Cartridges. He took good rifle cartridges and necked them UP to slow them down to handgun velocities, largely negating the benefits of flat trajectories, etc. This was done to make them subsonic and quiet, which I suppose is worthwhile for some people. Why not just load pistol cartridges like 9mm and 357 Mag or whatever with extremely heavy bullets? To my mind J. D. Jones is perhaps the most overrated, if prolific,?Wildcatter. Not saying this is bad, because any Wildcatter at least adds to the repository of reloading knowledge, but I'd rank him behind every other Wildcatter I know of.
