Previous posts on this thread reflect considerable confusion about swaging bullets from cartridge cases, and the equipment used. Since the Original Poster specifically asked about making .22 bullets from empty Rimfire cases let's start there: The date is early 1940's, and WWII. War demands halted production of commercial type bullets, which were soon in short supply and hard to obtain. However, fired Rimfire cases were relatively plentiful due to consumption of Rimfire ammo in marksmanship training centers such ROTC programs. Thus, Fred Huntington and other like minded shooters made bullet swaging dies to convert these fired cases to finished bullets for themselves and other shooters. Existing reloading presses at the time were generally not strong or rigid enough for the stresses of bullet swaging so Huntington designed and built a more robust press for the swaging dies he wanted to make and sell, and the Rock Chuck Bullet Swage company was born. Very few of these were built, and extant survivors are mainly in vintage collections. At the close of WWII commercial production of bullets for reloaders resumed, which of course resulted in a drop in demand for bullets made from Rimfire cases and swages to make them. However, Huntington and other reloaders forsaw a growing market for reloading presses and loading dies, at which time, about 1947, Huntington revised the design of his press. It is what I refer to as the RCBS 2nd model, which is easily identified by the rigid side braces. A photo of the 2nd model is attached with the lower unit of an original Huntington bullet swaging die in place. Also attached is photo of original .22 cal RCBS swaging dies, such as would have been used making bullets from Rimfire cases. The third attached photo shows the swaging dies in place in an early "A" style press. Forth photo is an early "A" which were introduced in mid 1950's.
