    Has anybody tried to tune the Crown in .30? I know plenty of you have tuned the .25 to 140 bar and set the HS to max but is there anymore performance to be gained in the .30?

    My reg is already set at 150bar… I guess I could max out my hammer spring but it seems  to me with the gun already hitting in the 880s in terms of FPS, I’m already in the “sweet spot” for velocity and accuracy.

    First question is what is your goal with tuning? More accuracy or more power?

    I believe the FX Crown manual states that 150 bar is about the limit on the reg. If you're already shooting those 44 grain pellets at 880 fps, that's right in the sweet spot for those pellets. I have a Matador R5 .30 and I'm able to adjust the velocity of the pellet with the HST up to around 900 fps, but ultimately I'd recommend you leave the reg at 150 and just play with the HST settings to find what FPS your gun likes for best accuracy.

    I have a Crown in .25 and thought of increasing my reg a bit to be able to shoot MK II's as well but so far I'm happy with the accuracy I get out of the box with the stock settings with the JSB 25.4g pellets. If it ain't broke, don't fix it.

    Mr. Rowe just did a new heavier hammer assembly video for the Crown in .30. He got the 44's out at like 940 FPS!
