Chamois thanks what I have suspected but it is so infrequent to catch a bullet of either type it is hard to compare them. I also think the ones you do catch are biased towards the ones that expanded more but couldn't prove this.
"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
