1. They didn’t “order” that much, they have a contract that locks the price in for up to 450 million rounds for an extended period of time. In other words, someone isn’t shipping 450 million rounds to someone this year, they are just locking in the price for future orders.
2. Sounds like a lot, but it really isn’t. Let’s just take the US Army for example. They have about 1.5 million active and 1.5 million in reserve. Let’s just use a clean 1 million number. If they blow off 50 rounds of pistol ammo per week in practice, you are looking at billions of rounds used.
3. I believe that some agencies are standardizing calibers to the .40 (mentioned this yesterday as having read this in several LEO forums). Over x number of years to replace the ammo plus practice, etc, you can burn through 450 million rounds rather quickly. Even considering the armed agencies that fall under DHS- FBI, Secret Service, Coast Guard, etc (not counting for if the contract extends beyond DHS).
You seem to have all the details.
Extended time? Not being shipped this year?
How long?
When is it being shipped?
US Army for example.... If they blow off 50 rounds of pistol ammo per week in practice
If ya think everyone in active duty/non-activy duty U.S. Army are blowing through 50 rounds every week, for target practice, you're in lala land.
