In this tutorial, we learn how to film realistic and bloody gun shots. You will first need to gather up all the materials you need to make this happen. Once you have everything ready, set it all into place. Make sure you have the fake blood placed in the shirt where the person is pointing the gun, and also make sure you have a good actor. After this, use a firecracker to make the sound of a gunshot. As soon as this goes off and the person pulls the fake trigger, have the other person push on their torso to release the fake blood. After this, you will have a great gory scene without any harm!
