Of course, DHS bought about 100 million times more ammo than I did, and they don't shoot at paper targets for fun and recreation. Is it shocking to a non-gun owner if I said that I store about 5,000 rounds at any one time? I hope not, because that's much less than a one year supply. If I only shoot one box (50) once a week, that's 2,600 rounds. If I want to be competitive, just to maintain my skill level, I have to shoot more than once a week. Depending on how much dry fire I incorporate into training, I shoot about six times that amount, or 300 rounds per week, or 15,600 rounds a year. If i really want to improve, I have to train daily!
In addition, stockpiling ammunition has been a necessity given the Federal government's interventions into the ammunition and components market in the quest for gun control. .22LR rifle ammunition, my mainstay, is essentially unavailable. As I shoot up my supply, you can bet I will stockpile whatever I can find in that caliber. How does that make me a terrorist?
