Joerg's new toy.

I fooled around with this cartridge design decades ago but gave up because it was long before 4500 psi handpumps were available. This sparked interest in it again, maybe with a 40mm size cartridge 8-) ... maybe rimless for better feeding in JSR's brain.

Thank you for sharing this video - I didn't know that these cartridges existed. Surprisingly, I was unable to find an internal diagram, so I ordered a couple of them and will post photos of the internals when they arrive.
