I wondered about that train of thought Patrick...

I'm still wondering...

Just look at the following pics made today with my LP08, which I carefully arranged so that the magazine had the same angle and vertical position as if it were inside the pistol.

Attachment 47161
The bullet is a copper-plated type (fairly soft), and in the close-up you can see how the nose was slightly crumpled after hitting the edge of the chamber.

Attachment 47162

As the bullet is pushed out of the stack, one imagines that any distortion of the magazine lips (or maybe just plain dynamics and manufacturing tolerances) might even allow the bullet to tip up a few degrees more. With an ogival nose this is hardly a problem, as there is always a curved surface to contact the chamber and lead the bullet in, never an edge.

So, for me, the suspicion remains that the reason put forward:

feared that the Allies might consider the truncated bullet a form of Dum-Dum bullet and retaliate

was a convenient face-saver.

I.e.
"It worked fine, but others wouldn't let us"
was politically more acceptable than
"It didn't work so well, we got a lot of feeding problems".

Does anyone have documentation to indicate that there were feeding problems with the truncated cone ammunition?

This is a translated facsimile of the directive from the war department replacing the truncated bullet with the ogival bullet.
