The Hague Declaration of 1899
The Contracting Parties agree to abstain from
the use of bullets which expand or flatten easily
in the human body, such as bullets with a hard
envelope which does not entirely cover the core
or is pierced with incisions

Dèclaration de la Haye 1899
Les Puissances contractantes s'interdisent
l'emploi de balles qui s'épanouissent ou
s'aplatissent facilement dans le corps humain,
telles que les balles à enveloppe dure dont
l'enveloppe ne couvrirait pas entièrement le
noyau ou serait pourvue d'incisions.

Case
In 1989 a man killed his son, his ex-wife and her boyfriend
and finally killed himself when confronted by a police
officer. The child was killed with a hunting rifle, but the
couple and he were killed with his Home Guard rifle, a
M/75 rifle, the German Heckler and Koch G3, using
Danish service ammunition produced by the State
ammunition factory, the “Ammunitions-arsenalet” (AMA)

Experimental confirmation
Tests were conducted at the Army Combat School, Experimental and Safety
Section, confirming the fragmentation of the M/75 bullet in ordnance gelatin

Collection of Danish cases
Having obtained the necessary permissions all know fatal
cases using the M/75 were collected. The results confirmed
previous reports – they were all fragmented.

The problem
Having drawn the attention of the manufacturer to the fragmentation of the
Danish ammunition an redesign was performed, after some discussions,
however.
The M/75 bullet was of similar design to the German bullet, a natural
decision since the weapon was German. It had a steel jacket with a
thickness of 0,35 mm.
The redesigned bullet is of a design very similar to the US bullet, not as a
result of copying but after considerable experimentation. The need to follow
NATO standardisation requirements led to a similar solution to the similar
problem. The new M/94 bullet has a tombak jacket that is 0,80 mm thick

The ”Scandal”
A year after the publication of the findings, a newspaper
happened to read it, and suddenly the front page was
decorated with a story that the Danish Defence used Dum-dum
bullets. The redesign was fortunately under way, but the
Minister of Defence had to take action, and ordered a recall of
all cartridges from Danish Forces in international operations –
ex-Yugoslavia – and a purchase of a large number of bullets
from a foreign manufacturer to be fitted into Danish produced
cases, until the new bullet could be in production.

First Ballistics and Wound Ballistics International Congress, Lyon, 16-17th June 2014
This bullet, that is now the standard 7,62 x 51 NATO bullet in
the Danish Defence is still in use as M/94, and has been
proved to fulfil the requirements. I was allowed to publish the
experimental work leading to the new bullet.

will be a NATO-certified non-fragmenting
bullet.

The – moral - dilemma
What will YOU do?
Call your MoD to tell them to buy new bullets and
scrap the millions in the depots?
Is that a wise move – career-wise?
Or do you shut up and hope nobody notices?
And what if someone else finds out and they ask you,
the expert?
And so on and so forth……
