if you really wanna see what the barrel is doing upon pulling the trigger, put 3 cartridges in the cylinder alternately. One in, skip one, one in......
Get ready to shoot, open the gate and turn, not spin, the cylinder blindly. You won't know if you are gonna touch off an a live round or a empty cylinder. It'll tell on ya bad.
Don't just cock and aim again, cause you know what's gonna happen next. Open the gate, turn the cylinder a bit, and line up and pull the trigger again.
