I have a Gen 2 Leshiy .22 everything is stock. If I turn the HST down to minimum and back out 2 clicks to I’m shooting JSB 15.9g at average of 544 FPS after 12 shoots with high of 548 and low 541 which is giving me around 10.5 FPE. Do I have to adjust the Reg or get the Huma? Will I hurt the gun by only adjusting just the HST to get it down to this low power? It’s using less air and just wanted to keep the power down for pets control.
