...And the classic bloviation* on the topic runs, "If you assembled the rounds you shoot someone with, it indicates premeditation..." (followed by references to villians in detective novels hand-carving "dum-dum" lead for their "gats," etc. etc.).
More to the point, Major Brand JHPs are normal, ordinary stuff of consistent and demonstrable performance available from most any gun shop. The stuff you did in the kitchen, you can't prove too much about in court without hiring an expert -- and even then, there's no assurance the rounds you expended weren't some special ++P++ exploding tracers (or whatever it takes to make the jury shudder). Why make the prosecuting attorney's work any easier? You were just an innocent average person, buyin' what the nice man behind the counter told you to buy.
Reloading is a great way to save money and get better performance at the range. Maybe not for the street.
