Pump Player has it right^^^^
Autocockers have to run at the right pressure and sweet-spotting your regulator is an important step in tuning your Sniper into the face-painter you are looking for. Sweet-spotting will take only about 15-30 minutes. When you are done, your Sniper will shoot quieter, more efficently and consistently.
To start you will need a place to shoot, some paint, Allen keys, a Chronograph and some air. If you field has a Chrono station/ range, it is a great place to do this tuning.
Start by turning your IVG (Internal Velocity Govenor or the velocity adjuster on the back of the frame) open up until it is loose, then give it one turn in.
Next turn your regulator all the way closed, not tight, just until it touches, then open it up 1turn.
Gas your gun, shoot three shots over the Chronograph. Now adjusting the regulator 1/2 turn at a time continue this process, your velocity will go up and up and up....then down. When it starts going down, fine tune your regulator until you reach maximum velocity. At that point your regulator is sweet-spotted.
Now your velocity should be high, too high - now use your IVG to adjust your velocity down to your field limit. When you change paint, conditions change or use a different barrel back, only use the IVG to adjust your FPS.
After you shoot a few cases and get your regulator broken-in, re-check your sweet-spot. At this point, you should not need to mess with it for a long time.
