I took a tour of a local ammunition factory we had nearby, and yes the two progressive presses in the guys basement was a factory. There were no records of anything that I could see, nor testing either, in fact after that day I wouldn't shoot his ammo if it was given to me. I also wouldn't trust what he would have claimed to be in them, but he sure sold a lot of them in every gun store around.
Things must be tuff in your area. I can't even remember when the last justifiable defense shooting needed exemplar evidence, or even went to court and you have two of them in your area at the same time. In fact we had a major case that did go to court shortly after Ohio passed its "Castle Doctrine" law. The defendant claimed self defense, but was charged with murder, and rightly so, and the ammunition he used was the least concern.
On another note, If there are new reloaders that may benefit from this subject, maybe we need a stickie of all the countless pages from the previous threads. They have all the same, or very similar, information as given above plus a whole lot more. The topic is based on fear-mongering and not on fact and all boils down to "do you believe it or not?" Or we could let this one go and start a new thread on how many imaginary things can a prosecutor say that will make you look bad in front of a jury, this one has been beat to death. Oddly enough, when I first read Dean Grennell write it nobody paid any attention to it at all, he must not have been that popular.
