“NeilClague”If any pellet breaks the sound barrier you will get a loud crack and no muzzle device will prevent that, the only way to stop that is to turn the power down or use a heavier pellet, Neil.


I agree with what you are saying about the small sonic boom that happens when using lighter pellets and going above a certain fps. I would use heavier pellets on high power to get the speed down, and would have you make me an lcd . Would having a longer , say 10 or 11 ” lcd and keeping the pellet speed around 900 fps keep the bark down Neil ?
