This happens when sweetspotting your system. Start with super low pressure (use a chrono) and slowly start increasing pressure until your velocity stops increasing, this is known as the sweet spot, where you will get the best efficiency/consistency from you reg,valve,spring setup. If you keep going past that sweetspot your velocity will begin to drop, which is due I believe to the increased pressure causing to cup seal to close faster and reducing your velocity. Hope it helps, look around the forums and you'll find info on how to do sweetspotting. It's definitely worth the time I put into it. Razor : I have a Flash with low pressure setup. The gun was shooting fine until I decided to remove the venturi from my stock bolt. After that the gun wouldn't recock. I figured more air was coming out of the bolt and less to recock so I turned up the air pressure on my regulator until it started recocking again. I fired across my chrono and it was only shooting 220 fps. When I turned up the pressure 150-200psi higher the gun started shooting about 180 fps. : Obviosly I'm not an airsmith because I have no idea what is going on here. Can anyone give me an explanation (or theory)of what's happening. : THANKS
