Ever since the Grand Theft Auto franchise burst onto the scene, gamers have been divided into two main camps – those who revel in the ability to roam the open world and cause as much mayhem as possible, and those who prefer to follow the in-game missions and storyline.

However, we mustn’t forget that there is actually a third group. It’s time for you to meet the gamers who like to test the limits of Grand Theft Auto V in order to research just what the game will or won’t let you do. The GTA kills video above is a prime example of this type of investigation. Needless to say, the results are fascinating. And very bloody.

The gang over at YouTube channel Vucko100 have decided to put the game’s weapons to the test. How many people can you kill with just a single bullet? As you can see in the video above, Vucko100 has found an answer. They even tested it with multiple different guns. And as you may have guessed, they quickly discovered that the test worked best with a sniper rifle.

This video just might convince you to test out some of your own GTA theories.
