I prefer to choose certainty of reloading components on hand over uncertainty of anything.
Who knows, ISIS/ISIL is trying like heck bombing all over Europe/Middle East and DHS/FBI/Border Patrol/US Marshalls added to PD/SD and military COULD order like 100 million rounds of ammo for war against ISIS/ISIL if any bombing occurs in the USA. That alone could trigger a retail shortage for a while.
I think while supplies are good and prices low, stocking up is a good idea.
This hits the nail on the head!
