 Okay, explain to people why, well, first of all, 5.7x28 is a really interesting, cool cartridge. It's a smaller cartridge. It's high velocity, small bullet going fast. Why do you like that over the .223? Well, I did the sheetrock test you're always talking about. It punched through, at five feet, it punched through the first sheet, and the second sheet had a dimple on the back side.
