thats the kind of results i would have expected. Interesting too is the tip and how it always gets sucked into the center and can turn sideways. As simple as that "plastic" tip it, it actually causes a great deal of weakness in the center of the bullet when it turns sideways. We experimented with solid brass and steel inserts that had smooth shafts and same result as the plastic. They just turn sideways and eat into the center of the bullet, weakening it. Gotta be threaded!
