A curious thought that ive always had and never bothered to ask. So now I turn to my fellow FTFers. Why are prices of the .25auto and .380 rounds so high? Both being a rather small cartridge with an average price around $20/box of 50rds, I cant understand how it is cheaper to shoot larger rounds like 9mm? Is it because they are not as commonly used? Is it a supply and demand issue?
