Spats and Frank - it's great that you guys are professionals that have dealt with this sort of issues. I am but an enthusiast and one who likes to question the norm. I can ask all day why this is not allowed and try to find loopholes. It's not meant to be in any way disrespectful or annoying. It's more for the education. Whether I'm wrong or right is not my biggest concern, but whether I learned something.
What I've taken away from this thread is most people are not overly concerned about having to explain to a jury their ammo choice. Their concerns is more about having ammo that is effective and functions with the gun of their choice.
