One of the few things that looked good on paper but also worked well in the field. In order for a bullet to perform well, it has to have a few weaknesses. If easy opening is a weakness. I have never had one fail me. Many people complain about the way the bullet performed inside the animal. This means it was killed and they got to look in side. I should add that the Barnes X bullet is a Penetrator where the Partition is an expander. You hardy ever recover an X bullet. They are however a good bullet that seems to do enough Damage to get the job done.
