Fx royale 400 reg pressure for 935 fps?

[mubhaur]

I have regulated royale 400. Reg is set at 143 bars. The guns max out to 900 fps with JSB 18 grain pellets. 

Should I increase reg pressure to 150 bars to get 935 fps using same jsb 18 grain pellets? 

what your royale 400 regulated do max with 18 grain pellets?

Yes now I am getting 935 fps at 145 bars reg pressure with 18 grain JSB. 

It just needed a but of cleaning of internals, replaced regulator internal O rings. This is back to perfect service again.

thanks guys.
