.50 AE=handgun cartridge for the Desert Eagle semi-auto, camparable to the .44magnum, maybe good to 50yards. A little too much recoil to get an effective follow-up shot for personal defense.

Jerry was having the time of his life when he got to shoot the .50 at the range.

Steve was pissed when he missed the buck of his life when he missed with his .50 caliber black powder.

I'll know that I have made it when I can blow $1,500 on a DE .50AE show gun.

The bear was pissed and chased me until I opened up his chest cavity with 6 shots from my .500.

.50 Caliber 

A bullet that is very long and powerful. It is used in some sniper rifles (like the Barret .50 Cal) , AA guns, and sometimes chainguns or mounted machine guns. The bullet is about the length of an average middle finger. It is used to take down vehicles and armored personnel. This munition is not commonly used against lightly armored personnel, but it can still take someone out with one hit.

50 Caliber 

1) The round that strikes fear into the enemy. You don't want to be out when one of these is flying in the air.
2) Amazing dubstep song by FuntCase

1) "This...is the .223 round. It is the standard round for military units. This...is the .308. Now, it is the standard round for the AK-47. And this...is the 50 caliber round."
2) "The bass drop was so heavy on '50 Caliber'"
