The shortage is due mostly to panic buying and associated hoarding, like the supermarket buying just before a snow storm.
If and when the SHTF, food is going to be just as difficult to get....
Yes that’s the lesson to be learned here, I think.
The big question on the gun and ammo panic is - why the sudden panic?
Nothing sudden or panicky about it. It’s been underway since 2009. The current occupant of the White House made no secret of his intent towards “fundamentally changing” the United States, its economy, and its form of government. He is now busily engaged in building and arming his own national security force (DHS) to be used in furtherance of those goals, and to counter resistance from the American people and its citizen soldiers. Accordingly, many folks simply understand, something evil this way comes, and are preparing for a long twilight struggle for freedom.
