Well I put PCP tunes extreme flow valve on a ace care cf bottle filled to 3600 psi 24in unchoked 250 barrel 14 in talon tunes shroud tried it with 59 grain nsa bullets I was surprised on how loud it was even with the shroud and a loud crack also which I'm sure broke sound barrier the way the crack sounded I didnt get a chance to Chrono them yet but I will have to find a heavier bullet if I use the .250 barrel
