I would never put myself in a situation where I might have to answer a question like that. For, I think, very obvious reasons.Is it not a hazard when the prosecutor asks what did if you self-load, and you describe a 147gr bullet in 9mm loaded to a velocity of 1200 fps and he counters with the non-existence of any commercially-manufactured round and suggests you purposely loaded that round with the intention of destroying another human being should the occasion arise, circumstances notwithstanding, of course, which suggests to the jury that YOU are the villain?
Some people think it will never come up, or perhaps feel like they have a really good answer. Everyone gets to make their own decisions.
I like to keep in mind that experience is something you get right AFTER you really needed it. I prefer to learn by other means. Experience is, without question, an excellent teacher, but at the same time a very hard teacher.
It was because there was no way for the prosecutor to show otherwise."If you find yourself in a hole,stop digging" "I do not know much about bullets" was a good exit.
For someone who spends a lot of time discussing ammunition and self-defense online or who can be shown to reload their own ammunition, attempting an exit like that could easily be shown to be disingenuous which could be very damaging to one's defense.
