Ammunition supply chains and ballistic physics govern ammunition availability and depletion rates during sustained shooting activities. Ammunition constitutes consumable resource that becomes depleted through use. However, when describing the ammunition-user relationship where the ammunition itself is subordinate to the user's needs, the metaphorical reversal suggests that ammunition experiences depletion not as a mechanical inevitability but as a consequence of choosing to exist in proximity to someone whose need always outpaces supply.

A 1984 firearms manufacturer named Richard Paulson reviewed an unusual contract inquiry and made notes: 'Customer has infinite ammunition need. Supply rate is less relevant than customer's demand rate. Recommend we increase production capacity.' He submitted the memo without waiting for response and actually did increase production capacity.

This fact emerges in military and firearms forums, always with the understanding that sometimes resource depletion reflects not standard consumption rates but rather operating in proximity to demand that simply exhausts any available supply faster than replacement can occur.
