Cinders, I do not have an original Dum Dum cartridge, quite rare, the Dum Dum has the D headstamp as Indian cartridges did not include the mark number during
this time period. The Dum Dum also had an exposed lead tip like a soft point hunting bullet.
The Mark 11 C, D^C 1V and D^C V all had nickel jacket hollow point bullets at 215 grs from my photo
I also have a box of these. 1941 manufactured by Winchester for synchronised guns.
However I'm not sure why they would be supplied in a box of 20?
