Like many, I always wondered why .380 cost more than 9mm. Online explanations by people of unknown background discuss how 9mm is produced in quantities that offer economy of scale. This is likely just one piece of the puzzle. It just occurred to me that all centerfire handgun ammo costs about the same, except 9mm. I can’t find a breakdown of market share of various calibers, but I’ll accept that 9mm has a disproportionate share of demand, exceeded by plentiful production (except for the current circumstances, of course), hence the supply/demand rule keeps the price lower than other calibers.
So I’ve been asking the wrong question. It’s not, “Why is ___ more expensive than 9mm?” It’s simply “Why is 9mm the low cost caliber.”
I did read that rimfire is about 55% of market share, and I’ll assume the vast majority of that is .22LR. So that economy of scale helps make .22LR cheap.
I also read that WWII ammo production was more than double today’s production, and the Lake City plant is the only one still operating, making 99% of military ammo, but that’s a different topic.
