What is .50 Beowulf?
A rather big cartridge used mainly for hunting, but also in some custom assult rifles in use with some special forces and in Magnum Research's BFR (Biggest, Finest Revolver, red.). It has been credited for taking down anything from racoons to wild boars and grizly bears - and suicide bombers.
It makes a very hefty sound.
Honestly, I don't wanna get shot with a .50 Beowulf - even if i was inside a Humwee
