Hi,

I have a regulated Fx Whisper with LW barrel. I'd like to shoot 16gr JSB pellets at around 275m/s. My reg is currently set to 140 bar. The transfer port in the block is 4 mm, the black valve spring retainer cap has a 5mm hole. With the hammer spring at max tension, I get around 259 m/s. Any way to get this to 275?
