In the latest Handloader issue #301 there is an article about loading for the Luger pistol.
It is stated that the original bullet was a 124gn truncated cone, and that the Ideal 356402 boolit is based closely upon it.
Allegedly it was produced into the beginning of WWI for the German military and into the 1930's for civilian sales in the US.
It would be of interest to be able to compare the "original" to the Ideal adaption for a cast boolit.
Does anyone know of an actual picture of this original military 9mm Parabellum bullet?
