Thanks guys =).
So say he goes my gun is set to 260 FPS, and i can have it at 280, how will i know how far to turn my velocity screw ?
Thats one thing i'm phased about lol.
Read your manual carefully. Learn how to adjust the velocity on your marker using the correct tool.
When you goto a paintball site, the marshall will make an announcement first thing to what the limit will be for there site.
The site will have a chrono somewhere on there site, of which you take your marker, paintballs and the tool to adjust the velocity(FPS).
ie. if the sites limit is 280fps, i suggest you chrono around the 265 fps. (purely because it is very hard to get a consistant 280fps for every ball).

Each time you adjust your markers velocity, shoot a few paintballs off (lets the pressure inside the marker adjust) before you re-chrono.

When your ready to get on field, marshalls may want to chrono your markers again, just incase you get some idiot wanting to shoot 350fps.

During the day in between games, re-chrono again, as the weather gets warm, the paintballs will expand slightly, giving you a higher velocity reading (FPS)
Also re-chrono if you decide to use different brand or batch of paintballs, as paintballs vary in size.

I always used to find with my pmr that turning the velocity all the way in, then turning it 2 and a half turns out would bring it to a level near 280, if not just keep turning it out gradually

hope that helps

As Nitro says the marker has a manual so give it a read. If you do not have a manual they are available via .pdf on the web.

The velocity will be adjusted via the inline regulator otherwise known as the foregrip reg. There is a grub screw that you adjust to allow more or less regulated air into the marker that will result in higher or lower velocity.
