Those of you who do not own a firearm may not understand the dynamics of the bullet supply. I imagine that you picture the typical gun owner as a kook just stockpiling piles of ammunition, and eventually sitting in a room surrounded by guns and ammunition, waiting for "the Feds" to come try to take it away.Stupid stereotyping.Actually, there are millions of gun owners who use their weapons on a routine basis, for hunting, sport shooting, and target practice. Granted, there are probably several million people who are new gun owners. They'll buy a gun and a box of ammunition. Hopefully, they'll take a safety and home/personal defense course, during which they may shoot a couple hundred rounds, if that.Then most of them will end up with less than 100 rounds and the single gun locked away. Of course, with 6.1 million guns sold last year [based on the Instant Check numbers], that's 600,000,000 rounds of ammo a year shot just "trying out the new gun".In the spectrum of ammunition users, the typical game hunter is near the bottom on ammo usage. They'll sight in their deer rifle annually, and take it into the field for hunting season [for deer or whatever]. If they shoot off a dozen rounds each year, that's a lot.Now we come to the target shooters and shooting sports, where the ammo crunch is felt the most. We are USING ammo. A single target shooter who goes out once a week, and shoots 100 to 200 rounds each trip, will go through 5 to 10,000 rounds a year. Practical pistol and tactical pistol competition amounts to about the same... for the competition alone. Practice sessions for many of these shooters can amount to 5 to 10,000 rounds a MONTH. These shooters are mostly reloading their own ammunition, which means that they are hurting when the components of the loaded rounds go into short supply. [Components include the unloaded brass, the powder, the primer, and the bullet that comprises a loaded round]. The ammunition makers use these same components, and all that extra manufacturing is sucking up the supplies from companies who make those components. And there are tens of thousands of us.That is pushing up the cost and depressing the available supply. A lot of people are compensating by shooting airsoft pistols and .22 pistol modifications of their full-power weapons to get in practice at a reasonable cost. So there's pressure on the supplies all the way down the line.I had to laugh when I read that bit about the guy who wants 1,000 rounds of ammo for each of his guns. Apparently, nobody bothered to ask him how many rounds he was shooting each month.So that's a brief rundown to allow the casual reader a better idea of why the ammunition is being produced in the quantities mentioned. For sure, the 9,000,000,000 rounds of ammunition produced a year aren't piling up in closets all over the country.
