The shelves are empty, except for a few select calibers. Those calibers are 243 Winchester, 30-30 Winchester, 270 Winchester, 7mm magnum, 45 colt and 30-06 Springfield. A line of people are standing at the counter in the hopes the store got a shipment in.
Sounds like something from a movie? Nope, its the result of panic buying after the Communist Dianne Feinstein talked about another gun ban in the wake of the Sandy Hook shooting.
The calibers left on the shelf share some common denominators, they do not fit semi-automatic rifles, nor are they chambered in modern day military grade rifles.
There are semi-automatic rifles on the market chambered for 243 Winchester and 270 Winchester, but they are not very popular with modern day hunters.
