This is why when I reload, I have no distractions. No radio, no cell phone, no nothing. If emergency means I have to stop, I will go back from the first die and check everything in order to find out where I stopped, even if I know where I stopped. It's the same thing when you shoot guns. You check your gun and all guns to make sure they are clear before handing them to anyone, or if someone hands you a gun. It doesn't matter if you checked it 10 seconds ago. You check it again and clear it.
