Well I finally put my Disco to the chrony.I drilled out the shot tube end-cap a quarter inch deeper to reduce power when I made a power adjuster.Using the stock spring and lowest setting I filled to 2000psi and shot until I reached my starting FPS,which was 506fps.Ending at 400 psi and racking up 112 shots before I hit 507fps again.The sweet spots was from 1400 psi to 700 psi getting roughly 50 shots with a high of 660 and a low of 620 back down to 615 at 700 psi and 50 shots.here's the full string.

This mod is great for 10 meter shooting,next I'll have to test it on the full power setting.
