Hello,
ELB: No, I was never an engineer, but majored in physics and math. Maybe that explains it? Hahhahahhahha!
roadster: "DPX" stands for Deep Penetrating X-bullet. The X-bullet, a homogeneous copper alloy bullet was first used in rifle rounds and having seen them used, can attest to their deep penetrating characteristics. Rifle rounds form an "X" shape when expanded as they fold back into four "petals." The handgun bullets have six petals, but the "X" designation stayed.
Best.
