I've read everywhere a lot of silly things about this venerable round starting from Lee who makes dies focused on .323 bullets and ending with people who say they shoot .323 mauser bullets with great accuracy in a .327-329 bored barrel.
If you take a look at the original french drawings you'll notice that the solid brass D bullet is a stepped one like .22 lr i.e. it has two diameters: .327 for the portion protruding from the case and .320 for the portion inside the neck while "N" bullet is a conventional .327 boat tail. Consequently the neck area in the chamber is bigger than the one of D chamber, just the thickness of the neck.
Until now I've reloaded only for my mousqueton Berthier 92/16 with its N chamber with no problem with .327 Partizan bullets(except for reworking Lee dies) seated with correct OAL, but yesterday I've got my Remington RB 1914 fortunately unmessed thus with D chamber. Until few months ago in France there were a lot of original WWI era D solid brass bullets but now the source is dry.
Crawling in the web I saw someone advertising 8 lebel PPU rounds loaded with Partizan D bullets. I couldn't believe it 223102223103223104so I assembled a virgin PPU brass with one usual .327 PPU bullet And I had the surprise to see the round enter easily in that D chamber. Then I realized the Partizan trick: not a stepped bullet but a two diameters bullet separated by the crimping groove: if you crimp the bullet at the crimping groove you'd get a "D" ammo but if you would seat the bullet more deep you'll enlarge the neck and you'll have an "N" round. Pure genius.
