Seems like they should have tapered the jacket more on the 165, but that is a pretty big hollow point behind the tip. I don't know how it happens but occasionally the hollow point of a bullet can get clogged resulting in little expansion. Don't know if that is a factor or not for the mixed reports?

"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
