Do you have the stock transfer port, or the Huma. I’m gonna try swapping out the pellet probe and transfer port before going into the internals.
If I’m not mistaken it’s where the micro sits that’s important, and a particular micro setting can be achieved with various settings of the macro. Right now my micro is usually adjusted between 4.5 and 5 (the top of the scale) with my 2nd reg set at 120 bar. Pretty sure I could lower the second regulator by 10 bar and still get 1000 FPS with a 25 grain slug.
This is good advice. Running a really high pressure may mean your gun won’t seal at lower pressures. I bought a mk2 that was all hyped up to shoot slugs with the reg running 170 bar. The valve got formed continuously operating at that high pressure and would no longer seal at lower pressure. Had to get the valve pin seal swapped out. Luckily the valve housing was fine. Just something to think about. Always best to stay within factory limits. If going outside is needed maybe bump to a PB rimfire.
Exactly, stating what the wheel is set at without giving the macro setting is pointless. You can set the macro to whatever and still change the micro to whatever without changing the macro.
Cheers mate I’ve got my 2nd reg set on 110 but wasn’t sure if running the micro 4-4.50 was too high or if I needed to up my reg
Yo Oz, Between me and a mate we have a 22,25 & a 30 cal. If your interested I have local place we can do testing with crono etc and get your tune right. Drop me a line
My 22 is set to 108 at the second reg. It's fps peaks out at a micro of 4, going higher does not add fps so going higher on the spring would be too much for me in that it's slamming the hammer faster than it needs to. Your mileage may vary.
