An ultralight category could be interesting. One of my better drone configurations fires a 35g projectile... at 900 m/s (range on 1m target under 900m). That doesn't sound like an effective weapon... except that the drone will usually be closing at ~3 Km/s when it fires. 35g coming at you at 3.5 Km/s is no joke coming from a relatively cheap drone (the weapon itself is under 100Kg).
I haven't tested my micro drone dispenser missiles since the last patch, so it's possible this has been fixed. But I don't remember seeing it in the changelog.

But sandcasters have extremely good anti-armor performance, at least anything that isn't multiple kilo-megatons of osmoiridium...

No, you have to manually turn on ignore range for it to be effective, often. This particular drone also has a launcher for ultracheap missiles, so often those distract point defense and it can get within ostensible gun range anyway. |

And my entries:
Here's my entry for the light category: 42 g, 8.6 km/s, 0.002° spread for a 9.22 km range against 1 m^2 targets. There's also a 100 MW version with platinum reaction wheels that's slightly heavier but far cheaper. And for the middleweight category... It's not gonna win any awards for accuracy, but it will ruin your day if you're on the receiving end of one of its 23 MJ slugs.

Projectile is only 24g, but total launch mass is 26.4g, still count? This is the very first railgun I designed, although it's been constantly updated and improved. Along with the projectile. Attachments:

someusername6 your designs have horribly low efficiency, you should aim for 30%+ if not 40%+

I aimed to maximize the range at which I can hit a 1 m target with a coilgun under the challenge constraints -- not on making an efficient weapon, or one that fires fast, or one that I'd like to use in combat.

I think the challenge requirements could be modified. Instead of requiring a specific shell mass, a required projectile energy would be better. This allows lower mass higher velocity railguns and would encourage more practical weapons.

This allows lower mass higher velocity railguns and would encourage more practical weapons. I think the intent of the original poster was to incentivize railguns / coilguns with a mass other than 1 g. I also think that requiring only projectile energy would give us very massive and slow projectiles from conventional guns. |
