I found myself wondering: what does it take to stop a vehicle with, say, less than 5rds? Will a .308 do it? .300 WinMag? Obviously there are a lot of variables, and a lot of solutions (like .50, etc.), but would a hunting type of caliber do the job?
I'm thinking that a reliable way to kill a vehicle's momentum quickly is to break the engine and ruin its compression, but idk.
