The Department of Fish & Game won’t let you shoot Bambi with full metal jacketed 7.62x51mm M80 ball because it would be inhumane.
The Hague Accords won’t let you use .308 Winchester 150gr. Ballistic Silvertips on enemy personnel because it would be inhumane.

I’ve never understood the expanding ammo prohibition in the Hague Convention. Flamethrowers, air burst artillery, high speed automatic weapons, mines, cluster munitions, napalm, NBC, FAE,………all known HUMANE ways of killing your fellow man. LOL!
