One option is to eliminate the Delrin ring altogether, but the o-ring will still be compressed by the gas pressure. Still, might give this a go before boring it out for 0.22".
Mmm but that would then mean it wouldn't seal around the front ring... mmm
Tricky isn't it? But once I figure it out, the world will be my oyster
having a more or less standardised self contained cartridge system will open up an unbelievable array of possibilities, look at what it did for firearms.
I also want to prototype something along
these lines for the pneumatically inclined.
