I’ve owned some pretty “outside the mainstream” calibers over the years, but in the last 5-10, I’ve tried to pare things down for some degree of standardization. Right now, about the most “exotic” chambering I need to feed is 10mm, which has always leaned toward the expensive side, but thus far, where I’m at, can still be found on some store shelves.
Part of the “plan”? Gun control through ammo shortage? High price IS a form of rationing. Is the Obama (mis)administration buying up ammo in LARGE quanities? Dry up the “fuel” (ammo), and you get defacto “gun control”.
