I decided to go ahead and keep the 30 cal. I ordered one of these upgrade valve kits off ebay.
Paul seems to know his stuff of the platform and has made a few videos of mods and teardown.
This should add 100 fps AND he says it will lower the reg pressure needed by 20-30 BAR which is a huge gain for the big bore. I'm currently running 170 bar and only getting 835 fps with 45 grain.
If this brings me up into the 925 range, I will likely cut the barrel down and go compact dirty thirty. Make some baffles to stick in the shroud and run it at stock length and bottle.
The choke is heavy on this gun and I think that's giving me fits with accuracy. It currently likes only the JTS 45.06 and fx hybrids. I've tried a few NSA slugs and it won't group them even at 40 yards.
If I can get it to shoot 44 grain hybrids in the 850-900 range, I'd be happy. I shoot pellets mostly anyhow.
