1 gram of Osmium for the sabot and 1.68 mg of Lithium for the payload = 99.83% Osmium in mass for mine.

I personally found 0% shrapnel mass needles could not penetrate anything but the weakest armor targets. Apophys's Gladiator has basically zero armor, lol. It's a glass cannon.

The little speck of lithium at 211 km/s goes through anything. I was using a lithium radiation shield on a spacer, like an earlier design of mine. Apophys had a pretty good flak based design posted in the battlefield thread. I added the code for my design on the first page. I'm surprised at how resource-intensive these projectiles are on the game engine. I get zero frames on a 20 round burst... with an FX-8350 4 ghz/eight core (I know the engine doesn't take advantage of that) and a RX 480. A smaller gun shooting around 56 km/s doesn't drop the framerate as bad. Screenshot below shows penetration on a target station. Shots went clean through 10m of boron, 10m of amorphous carbon, and 10m of vanadium chrome steel, with a few punching out the other side as well. Engagement range was 1.96Mm, due to target size. 40 rounds fired, not sure on hit percentage. I didn't count all the holes lol.

Yeah. It's been reported repeatedly that hypervelocity needleguns cause very frequent crashing. Probably something to do with the way they are modeled.

This discussion around needleguns / lithium flecks are as good of an argument as I've ever seen to ask for the expanding the following limits:
* Sabot mass under 1 g * Railgun rail length over 50 m * Railgun / coilgun power over 1 GW

It really puts a hard limit on coilgun projectile speed.

Huh, sounds like the game is counting the 50M spacer when calculating how slender the projectile is. This is soooo bugged it's awesome

Apophys had a pretty good flak based design posted in the battlefield thread. Hmm. I couldn't repeat your results even with my 71mg Osmium Flect-gun, then I realized the reason my less dense/lighter-projectile needleguns fail to destroy my target station (at least, before lag-induced crash) is because I was shooting at my NEFP target. Whoops. Let's try something more reasonable against my Graphogel Flect-gun. My gun. Annnd the conclusion... No (practical) amount of armor can withstand 200 km/s+ guns; even a hard diamond-top and high angle of incidence is meaningless.

so a needle with a spacer is whats called a flek gun right? newageofpower

Should I really explain to someone who doesn't give a rat's a** about the difference between power intensity and total energy? Hmmm... But I can benevolent on occaision. so a needle with a spacer is whats called a flek gun right? newageofpower Flect guns utilize a Spacer + (miniature) Radshield payload. Design a superfine, max power railgun dialed up to it's limits with the lighweight (sub 100mg) payload. Set length to 50m. Velocity, accuracy, ranges are interchangeable depending on desired barrel composition (Zirconium Copper for max velocity, AlLiCu for high velocity/low weight, etc). Heavier, denser materials may increase performance vs superheavy monolithic armor, but if you're not shooting at an asteroid made out of Noble Metals lithium/graphogel bullets will punch through pretty much anything else.

Just pointing this out... flect isn't a word, it should be fleck.
We need to do some digging and see where this idea spawned
