Bullet flight time conventions

This is true, but I think 'glide path' isn't really the best way to think about something that's only up for a handful of seconds.

Also, steadily shrinking area it can reach applies in much the same way to high-speed missiles. Even ignoring the eventual exhaustion of their propulsion, they (like a smart bullet) will inescapably overshoot the target. As the remaining range to the target decreases, so does the space the missile can maneuver into before such maneuvering becomes irrelevant.

It pays to ask the questions and nail down how it works and of course it is GURPS so it can work lots of ways. I am just skeptical of some of them. :)

Teleporters and some kinds of magic would probably make the seeker lose track of the target. At which point if it's not a lot smarter than I'd expect in a bullet-sized package it probably will either fly dumb or attack something that was right next to the target when it disappeared.
