In addition to the issues with a gyroc that guides by blind dead reckoning, I wouldn't really want to trust the sweep of the muzzle to be perfect and smooth enough to be on target at long range. Also, if you're skipping having a ranging step, so the gyroc has to fly along the arc traced out by the moving bearing across all ranges, that's not going to be a super efficient flight path at long ranges.

Re: Different Gyroc Designs
I was more concerned with the smarts required in the bullet, not in the gun (the gun also needs an acceleration sensor, which is harder for something handheld than something mounted, but probably within the capabilities of modern hardware, let alone TL 9).

Re: Different Gyroc Designs
It occurs to me my curving gyroc idea would probably be better served getting its input from a rangefinder, which should be able to calculate the target's velocity to determine the angle at which the gyroc needs to curve to stay on-target. That's going to be more reliable than expecting the shooter's aim to be stable enough.
At what point do you feel the full bonus (+3) is appropriate? If we have a decent value there, we could come up with the ranges at which it would get +1 and +2. For example, if +3 is appropriate at 2000 yards, that's normally -18 to hit, indicating a +1 for every -6 is appropriate. Of course, now that I think on it, there's probably no range at which the +3 bonus is appropriate - an SM-6 target 10 yards away looks the same (in a featureless plane) as an SM+12 target 10,000 yards away, and indeed both are at -10 to hit. It's kind of hard for a rangefinder to give you better hit chance than a same-size (by perception) target that's close enough that time-to-target doesn't matter. If may be more realistic to only allow a rangefinder to reduce any penalties due to the target's speed (or introduce a rule that gives time-to-target penalties, and let rangefinders reduce those).

Re: Different Gyroc Designs
If you have an integrated rangefinder, you'd just have the gun aim so the gyroc doesn't need to curve at all.

(There is, frankly, overwhelming evidence from real-world military practice as well as basic theory that range information is important in gunnery.) I don't get the thought-process that led to the conclusion that range-finding is irrelevant against stationary targets, but it really should be extremely obvious how wrong that is.

I found an article I wrote on why rangefinding matters. Be warned of annoyingly written equations. |

The idea of these self-aware projectiles that cancel out known factors but aren't guided towards the target is almost certainly more complicated than one that homes on a laser desgnator. Incidentally, UT doesn't have laser homing projectiles but they probbaly would be a superior TL9 solution to what UT does have.

We're getting into a pretty serious digression from the topic of gyrocs at this point, however. My apologies for the derail.

Of course, if you don't have solid prior information about the target's speed then you really need that range information to figure things out. Quote:

Also, given GURPS speed/range penalty mechanics, there usually isn't any penalty for target speed in long-range shooting. Speed of sound at sea level is less than move 400. Basically, you've made rangefinding exclusively useful at short range.
