Thanks.
I don't know for sure if these bullets were intended for use in a Luger. They came along with my old Belgian Browning Hi Power which was purchased many years ago from a guard on a Naval base. Since one of the cartridges was obviously from 1918, I thought they might be relevant.
Measurements are all outside measurements taken with calipers, not a micrometer.
The Rem-UMC 9mm cartridge:
Meplat - 0.170 inches
Cone length - 0.305 inches
The Western 1918 9mm cartridge:
Meplat - 0.180 inches
Cone Length - 0.310 inches
Peters 9mm cartridge:
Meplat - 0.175
Did not really have a cone. Was more of a rounded flat nose.
For comparison.
Lyman 356402:
Meplat - 0.180 inches
Cone Length - 0.340 inches
Projectile OAL - 0.615 inches
You can probably look up the specs on the Lyman 356402 mould, to see how close my measurements really are.
I would think somewhere out there you'd be able to find the specs for the original 9mm Luger truncated cone bullet. Might even be found on a Luger forum.
