FX crown port 30 with lower reg or ...?

Hello

fx crown owners, did you setup your reg up +130 bar for .22 or using .30 port for get faster speed and use lower reg pressure.

with 18.13 grains + port .30 you can get 10 m/s more than .22 port.

I had mine tuned for the 25 grn monsters/ slugs at Utah Airguns. They set the reg at 145 bar and the power wheel at 25/30. I’m very happy with this tune with both 380 and 600 mm barrels.
