9mm Sabot AP/PDW ammo Ammunition <20mm

A very cool 3D Print project I came across on twitter. I have long thought a 9mm sabot round would be nifty, and this guy is making it happen.
Twitter link has videos of projectiles being loaded and fired through IIIA and gel.

Current downside is the projectile is 0.25, and that due to thickness of sabot base projectile length limited to ~12mm.
Will be interesting to see how the project progresses. But already ballistic performance is well above 5.7, while retaining 9x19 compatibility.

Company makes 30 to 22 sabots , i guess 9mm is not popular enough

Yes, they were the sole source of sabots in the US. Based on the Remington accelerator design, idea was hyper fast .22s from 30-06/.308.
They did find some use in 7.62x25 tok:
A .355 version that could work with 9mm and .357 would be awesome, but so far no one is risking the $ for injection mould tooling.

Surprised smg762 hasn't chimed in yet.
Some of the parts we print are treated and used as tooling for RIM (Reactive Injection Molding) boxes. The owner was saying they told him they were hitting 30 tons pressure and working fine. Don't know if that's high enough for sabots, but the cost of producing tooling for lower volume production is going down.

Thats great to hear.
I was looking into injection moulds for a few products I designed a few years ago, and mould tooling was really prohibitive cost wise, at least for a one man biz.
If they go down in price I'll have to look back into those projects.
