Define "expiration date" in the context of ammunition.

In the context of ammunition, the expiration date is primarily concerned with safety and performance standards. This date signifies the point at which the manufacturer can no longer guarantee that the ammunition will function as intended, adhering to established safety criteria. Over time, various factors such as moisture, temperature fluctuations, and age can affect the chemical stability and structural integrity of the ammunition components, like the primer, powder, and casing.

Once the expiration date has passed, there may be increased risks associated with using that ammunition, including the potential for misfires, duds, or failures to fire altogether. Therefore, adhering to the expiration date is crucial for ensuring that ammunition performs reliably and safely during use. Other options touch on different aspects of ammunition, but they do not accurately capture the critical relationship between the expiration date and the safety and performance standards that ammunition must meet.
