That's pretty good for a small projectile! In the book they say part of why it's called a Smart Gun is that the rounds are IR-guided, and could be programmed to ignore specific heat signatures (in the book, they were programmed to avoid humans). That projectile has to have a guidance package, small thrust squibs, and still have enough energy to kill its target!

...and I just thought, that might explain the different sound the Smart Gun makes -- it's the guidance thrusters firing. They'd just be tiny little shots of gas.
