I have a new RTpro with X-valve, lvl-X, and ULT. At the chrono. I get a shot to shot range of about 40fps! Ranging from 266 up to 305 (These were back to back shots!) The normal range is not always this drastic, but still has a range from ~270 to ~290fps and rarly less then +/-8 fps . These shot are without holding the trigger before the 2nd shot and with about a 1 second rate of fire. When I hold the trigger, the way a Mag is suppose to be chronographed, the results are just as erratic.
In an attempt to diagnose the problem I have used 4 different air systems:
*2 Centerflag Dynaflow tanks with a regulated output of 850psi
*Nitroduck Megareg with a regulated output of 800psi
*PMI screw-in with a fixed output of I believe 800psi
I have also tried 2 different barrel systems:
*Stiffi Switch Kit with a .691, .689, and .687 back (.685 not used due to paint size)
*Dye Boom Stick with a .689 back
I have also tried many different paints: Draxxus Blaze, PMI premium, and many others.
None of this has fixed the problem!
The most frustrating part is that when I first received the marker and after I sent it back to the factory I received a printout from their chrono with 3 shot speeds. All of which are +/-2 fps. I have never seen results like this over the chrono.
Please help, at this point I am willing to try most anything short of throwing the gun out the window. :confused:
P.S.: What is the normal range of fps on a mag?
