When I shoot at the range, I generally buy a "brick" of whatever ammunition I am going to use on the range. I expend it there and then, but keep a box of 50-100 rounds available for the weapon at home (I use different rounds, so I usually have at least two kinds, ball and hollowpoint). I rotate that stock by shooting up what is at home, then replentishing the box at home from what I bought for the range. I do not, however, stockpile ammunition at home, so I would never have 1000 rounds of anything for more than a day or two. This shortage is quite typical of such shortages - it is temporary, and limited (usually geographically). It is also self-perpetuating. Manufacturers, however, report a significant increase in production.

The Great Ammo Shortage Of 2013 Continues:
Gun manufacturers are working nearly around the clock to keep up with demand. The number of guns and ammo made this year is more than was made in 2012, Guns.com notes. The amount of ammunition and guns produced in 2012 was also reportedly more than made in the previous year.
