You call 5,000 rounds hoarding???
Any more than you need for a reasonable period is hoarding. Its the jerks out there that have bought massive and unreasonable quantities of primers and ammo that have caused the shortages. Just to feel good. Just to have more than the other guy. Just to satisfy some sort of paranoia. Just to show how clever they are. Just to make huge profits in the future.
The last one will teach these folks a lesson. The same sort of individual bought massive quantities of primers during the Hillary Panic of 1994. They paid up to $35/m for primers that retailed for $15/m at the time. Within 7 months prices dropped back to normal and they were stuck with product that they paid double its real value. Only recently have retail prices risen to that level, and mostly because of the cost of commodity metals.
Some of the folks with excessive stocks of powder and primers had better check the national fire code about storage of such items in their homes and their own insurance policies. Sometimes Carma works.
