I was just a couple of years into my handgun shooting career when a family member was kind enough to buy a couple of boxes of ammunition for my birthday.
They had driven all the way across town to find what I wanted. The not-so-cheap ammunition in the package was .38 Super, a semi-automatic pistol cartridge that wouldn’t fit.
When the present was unwrapped, there was an unfortunate sense of disappointment. When it was pointed out that I could just exchange the semi-auto cartridges for revolver cartridges, I had to explain that most stores have policies in place preventing the return or exchange of ammunition.
This is because firearm cartridges are explosive devices that can be tampered with, altered, or exchanged for an inferior product.
