No you haven't. You're not cool, you're not funny. Leave. Stop posting, just leave, you're obviously too young to be here.
Is there anything in the average house hold that can stop a 9mm, AKM round, and/or a .50 cal?
Why are some weapons/bullets measured in mm (9mm), and some in Caliber (.50cal)? Also, why is Caliber measured in decimal?
1. Many things. A stud in the wall, a thick piece of wood, a refridgerator or icebox, a metal sink or bathtub for instance?
Always assume the bullet will penetrate anything you hide behind though.
2. Naming issues. For example, the 7.62 rifle round is in mm, but if you measure it in caliber it turns out to be a .30, which is attributed to an entirely different set of ammunition (you've got .30-06 Springfield, or the .308 Winchester). Confusion arises in certain situation, like when you say .50 caliber. That could mean a .50 Action Express, or .50 BMG. There's a list of cartridges in 12mm:
