    RT spraygun

    I know this will be old ground for you guys but,
    I have a standard RT it's airtight has gas thru foregrip on off, solid line to field strip pin
    running pressures of 800-1000psi from a tsunami reg don't know what the velocity is on the chrono but I can adjust it right up or down low without leaking.
    Thats the good bit, the bad bit; it chops paint like a sprayshop gun like one ball in 5-10
    nubbins are good, barrel is a dye broomstick paint is Zap spank, other paint tried, diablo is worse. Weird thing is, even with a barrel full of broken paint, it still manages to fire a few balls without breaking them. One problem I've found is at the back of the RT valve is what looked like a broken grub screw, which I think should lock into slot in the back of the body. I figured that might be my problem as the LPR is allways turned back slightly from the line up marks on the LPR/ RT valve join. I have drilled out this snapped off whatever it was and inserted a short rollpin locked in with red locktite, this pin now slides into the slot in the tube of the marker and hopefully stops the reg from unscrewing, doesn't seem to have cured the chopping though.
    have not got level 10 but surely the marker should still work without this many breaks?
    Any other suggestions?
    Someone said timing maybe, how do you alter the timing and is this likely to help?

    Well, first off, you should get the lvl 10. Secondly are you talking about the z-lock pin that holds the valve into the rail? It wouldn't have anything to do with chopping.

    Timing a mag? Don't know anything about that...

      It's most likely not an issue with the gun, there's something wrong with your paint, barrel, or loader.

      when you look into the breach when the marker is aired up, can you see the bolt? Is the barrel's breach lined up right with the body's breach?
      Check your 45* elbow for anything that would impede a paintball's slide from hopper to breach.
      What hopper are you using?
      How old is your paint?

        Do the Tom Kaye drop test.

        Take one of your paintballs and drop it from a height of 6 feet onto concrete. Keep dropping it until it breaks.
        If it breaks within
        3 drops = brittle paint
        6 drops = average paint
        9 drops = tough paint

        This is from memory (and a memory about 15 years old) so don't quote me on it.

        If your paint is very brittle, you can toughen it up by leaving it in a bag with an open glass of water to let the shells rehydrate for a few hours.

          Yes the Z lock pin is what I'm talking about

          Thanks

            What hopper are you using?
            How old is your paint?
            Paint is new tough paint 9 bounces or more (Spank Zap)
            Will check the body barrel alignment
            Hopper is a very old double impeller by arrowprecision
            I think the answer may be a forced loader?

              If the loader isn't feeding as fast as the rt is shooting, the lvl 7 will chop the partially fed ball in half. Sounds like a new loader and the lvl 10 will be your best bet.

                Yep. What kind of loader is it? At that pressure you should be running around 12-16 bps. A revvy will almost keep up on the low end, but 90% will get you 1oo10 chops. Cram that paint in there and/or get a level 10.

                There's no timing a mag, except by changing the on/off pin which should generally be avoided if the mag is cycling properly.

                  I have re-worked the feed plug, turned a bit off the base and filed it to a more parabolic shape, this has helped, I've also fitted a viewloader evo hopper until I can get an egg or similar loader
                  turned the velocity right down and then back up until I've got the range I want but no more.
                  I've just fired off a whole hopper of paint fairly fast with no breaks!
                  Maybe I've got it sorted?
                  I do love this mag when it works!

                    Glad it's on the road again! The older eggs topped out about 16 or 17 bps. If your bottle reg is running good, your power tube oring is loose, and your lube is right, you'll push about 19 bps at 1000 psi, so don't set it too high without a level 10 or a newer loader.

                    One reason to get a level 10 is that eventually you will get in a battle and forget to keep your loader filled. The last few balls fall at less than 13 bps. One of them will feed halfway. At least with a power feed half of it sprays out the vent like confetti.

                      I just thought of this... maybe you still have an older style feed plug. Wasn't there a problem with the original ones and AGD replaced them with a newer style? I think I remember reading somewhere that they upgraded the power feed plugs because of chopping issues.

                        He implied he had the older style, yes, but it sounds like he's got everything worked out. You just need a faster loader and/or a lvl10.
