Ive noticed that when I have the armamentarium on with the perk to carry more heavy weapons ammo that every time i die I lose a chunk of heavy weapons ammo in PVE.  I have only tested this with one gun, swarm, and it doesnt seem to matter if its at max capacity (115) or only half full, I will lose ammo on death.
