I’m thinking the secret is in the walls. Since printing a solid part is the goal, the walls provide the real structural integrity while the infill just acts as filler. With ‘rectal line ear’ it basically becomes one solid, continuous piece, making the whole thing way more durable.

I’m with you—I thought I could squeeze more out of 9mm, but I think I’ve hit a wall. You’re probably right that it’s time to move on to a better host like my Huxwrx 7.62.

I’ll DM you the site I use; I’d rather not post the link out in the open for everyone to see, because… reasons. If you see anything else on there that looks solid besides the Hux, definitely give me a shout. I’m really just trying to build a clean multi-cal setup that uses a standard thread adapter so I can finally get away from that 14ccw stuff

side note- why the AI re-write sound kinda human this time? lol

Back when I used PPS-CF, sand was my go-to for annealing—so much so that I still default to it today for every annealing. But that’s a tale for another day.

The modular nature of the Obsidian 9 platform makes multi-caliber capability attractive. Initial focus spans .22 through 9mm up to 300blk, with the goal of swapping baffle configurations rather than entire units for different applications.

Current 9mm prototype uses interlocking 60-degree cone geometry throughout the stack, complemented by specialized endcap baffles and silicone wipe integration. Performance exceeded expectations significantly—initial range testing produced suppression levels that suggested reduced powder charges, though standard loads were confirmed. The acoustic signature reduction was remarkable.

Next phase involves evaluating various mounting interface options once additional hardware arrives. This will determine optimal attachment methods and identify any compatibility issues across the intended caliber range.

Yes, I agree - it seems plausible. I believe they have a genuine opportunity for .22, so I’ll definitely research it further.

That’s really helpful, I’m grateful for the information. I’ll search for quality conventional baffles.
