I have HM1000X .25 60 FPE. I just installed .22 barrel and probe to shoot 18 grain pellets and 25grain redesigned pellets.
I reduced the TP size to achieve my desired fps but the gun is very loud.
Please guide me that how can I stop the gun from barking? Also it will help me give more shots.
I have minimised the HST but the gun still barks. The factory setting of reg is around 150 bars.

If you have a Reg setting fixture ? .... take the reg down closer to 130 bar.
Doing so the valve will open easier and less hammer weight and / or less hammer spring will be required. With less hammer strike the valves dwell will become lower as will the blast.
Even a change to the hammers nose length can be made longer effectively decreasing stroke and done with spring changes can reduce dwell. As will an *SSG devise * Highly recommended !!
There is MORE TOO tuning than this, but the general cause & effect still remain.
