Assuming one gun each. Also assuming each NICS check passed , each check was for only one gun, and discounting all private transfers in states that allow their residents to be adults (or as I call them, Free America). I would assume that 99+% of these checks resulted in a gun sale, due to the fact that most people with felony records don’t go to gun stores to buy guns.
The article also states that if each NICS check resulted in one sale, and each owner purchased 1,000 rounds of ammo, that would mean 14 billion rounds of ammo sold in 2009. That’s discounting existing gun owners who didn’t buy new guns in 2009. Kinda puts the ammo shortage into perspective, doesn’t it?
Now, for some fun with the numbers. Assume that each NICS check resulted in one gun sale, each new gun owner bought 1,000 rounds of ammo, and that the average overall length of the cartridges used was 1 1/2″. This means that if you were to place the ammo bullet to primer, the length would be… (works calculator) that can’t be right… (does calculations again) sweet mother of pearl…
331, 439.39 miles. That’s equivalent to the distance to Luna at perigee and halfway back. No wonder I can’t find .380 ammo…

And, all said, those are likely low numbers – both on the number of firearms per NICS check, and the number of rounds per firearm.
Hell, a thousand .22 is just a really good day

It must suck for the anti-rights advocates to see the writing on the wall like this…

That’s assuming that they can read the writing on the wall. So far, the anti-gun groups have been tone deaf.
