Nope. If you think about it for a minute, that is no more possible than grabbing your bootlaces, and lifting yourself clear of the floor.
As a collector, I usually drop into my LGS once a week. Sunday afternoon. Parking lot is usually 1/3 full. Last 2 months, it has been overflowing with cars. There are just a RECORD number of people buying guns, and looking for ammo.
The water and sewer system in a major city are the proper size for ordinary usage, with a good margin for growth, unusual situations, etc. The worry of the sanitary engineers is something like the superbowl. The game ends, and 75,000 men make a beeline for the bathroom. They all take a whiz, and within seconds, they all flush. AT ONCE.
Sewage system- instant overload. Water supply pressure- flatlines. System was just not designed for THAT many people doing the exact same thing, exact same instant.
Same thing applies to ammo supply pipeline.
