I don't know if you guys seen a issue of handloader a few months ago showing how a partition will out penetrate a high dollar A-Frame due to the front not being bonded. I believe it was Ross Seyfried who wrote it. I killed a moose with a A frame. It worked, the animal died. Don't think I will use them anymore. As far as the partition failing when losing the front. How in the world do you guys know what it was designed to do or not. I called Nosler and the rep said it is designed to do that. Maybe he was just telling me what i wanted to hear, maybe not. But you guys are strickly speculating unless you come from oregon and design bullets.
