Me either....stuff deleted...The only thing I can think of where people agree to only use certain ammo or not use certain ammo is the military in the Geneva convention.
That would be Hague Convention of 1899 John ...
Hague Convention of 1899
The peace conference was proposed on 24 August 1898 by Russian Tsar Nicholas II. Nicholas and Count Mikhail Nikolayevich Muravyov, his foreign minister, were instrumental in initiating the conference. The conference opened on 18 May 1899, the Tsar's birthday. The treaties, declarations, and final act of the conference were signed on 29 July of that year, and they entered into force on 4 September 1900. What is referred to as the Hague Convention of 1899 consisted of three main treaties and three additional declarations:
(I): Convention for the Pacific Settlement of International Disputes
This convention included the creation of the Permanent Court of Arbitration, which exists to this day. The section was ratified by all major powers, including United States, Great Britain, Austria-Hungary, Germany, France, Italy, Spain, Russia, Japan, and China.
(II): Convention with respect to the Laws and Customs of War on Land
This voluminous convention contains the laws to be used in all wars on land between signatories. It specifies the treatment of prisoners of war, includes the provisions of the Geneva Convention of 1864 for the treatment of the wounded, and forbids the use of poisons, the killing of enemy combatants who have surrendered, looting of a town or place, and the attack or bombardment of undefended towns or habitations. Inhabitants of occupied territories may not be forced into military service against their own country and collective punishment is forbidden. The section was ratified by all major powers mentioned above.
(III): Convention for the Adaptation to Maritime Warfare of the Principles of the Geneva Convention of 22 August 1864
This convention provides for the protection of marked hospital ships and requires them to treat the wounded and shipwrecked sailors of all belligerent parties. It too was ratified by all major powers.
(IV,1): Declaration concerning the Prohibition of the Discharge of Projectiles and Explosives from Balloons or by Other New Analogous Methods
This declaration provides that, for a period of five years, in any war between signatory powers, no projectiles or explosives would be launched from balloons, "or by other new methods of a similar nature." The declaration was ratified by all the major powers mentioned above, except Great Britain and the United States.
(IV,2): Declaration concerning the Prohibition of the Use of Projectiles with the Sole Object to Spread Asphyxiating Poisonous Gases
This declaration states that, in any war between signatory powers, the parties will abstain from using projectiles "the sole object of which is the diffusion of asphyxiating or deleterious gases." Ratified by all major powers, except the United States.
(IV,3): Declaration concerning the Prohibition of the Use of Bullets which can Easily Expand or Change their Form inside the Human Body such as Bullets with a Hard Covering which does not Completely Cover the Core, or containing indentations.
This declaration states that, in any war between signatory powers, the parties will abstain from using "bullets which expand or flatten easily in the human body." This directly banned "soft-nosed" bullets (which had a partial metal jacket and an exposed tip) and "cross-tipped" bullets (which had a cross-shaped incision in their tip to aid in expansion, nicknamed "Dum Dums" from the Dum Dum Arsenal in India).
It was ratified by all major powers, except the United States.
