I wonder if that's ever really been used against a lawful person in court. We've all heard it forever but why would it really matter? I think it's more likely just something someone made up and everyone else just repeats it.

Well sometimes old wives tales are true. I had a friend drown in a lake soon after he ate lunch because he cramped up. So take that for what's it's worth.
As far as the original question, I would say yes that it might be a "good shoot" by law enforcement, but you have to consider the civil action that WILL be taken against you by the perp's family, ACLU, NAACP, Whatever Group Dislikes you.... It is that situation that you would need to be concerned with.
Remember, in a civil trial you must testify... there is no "I plead the 5th".
You can do what you want, but I would stay away from it. I also think that that is the reason why there are no specs on reloading components released by the companies. I am sure they do not want the liability of having a lawsuit brought against them.
