The .223 and 5.45x45mm NATO cartridge family does have a lot of haters. These bullets are indeed smaller compared to the AK-47 variety or the even larger military cartridges. How well did these little bullets hold up to a cinderblock wall?
They certainly chewed up the wall, and eventually ripped right through. That tells you something about their capabilities.
