I asked my father in law about this. He has been a defense attorney for 25+ years. He said he had never heard of a case where the validity of using reloads in a self defense situation was brought into question. He did say that nothing is off limits however. He said if a lawyer was going to go after a guy for using reloads in a self defense situation, he would probably also go after the fact that the guy was carrying, had possibly applied for a ccw, etc. Basically, he says it would be like defending yourself with a custom knife. Just because you were carrying something better than you can buy at a store, it wouldn't mean you were intending to cut someone with it anymore than if it came from Walmart.
I look at it from the old viewpoint of the judged by 12, carried by 6 theory. I practice with reloads in my carry gun nearly everytime I practice. I carry the same reloads everytime I carry. Just my :2c:
