Just putting this out there for anyone curious down the road. JSB 18.13 on high power......very accurate. Chronograph was like 10 to 12 feet in front of muzzle.....due to high magnification scope. Could have squeezed out a few more shots with a full 230bar fill but you get the picture. First number is bar second is feet per second. Add 10 to 12 feet per second to all values for true muzzle velocity. This is my 10fps spread shooting range of pressure. For a 20fps spread I could have kept shooting.
