Spending the last few years obtaining a five or six year supply of ammo and reloading supplies for your various firearms when the stuff is readily available and often on sale can be one or the other of the following.
1. To one who has also stocked up over the past few years, it is "stockpiling."
2. To one who failed to think ahead and bought only enough ammo for the next visit to the range, it is "hoarding."
As with most things, it all depends on one's perspective.
