My RT paintball soup maker..HELP!

[magking1971]

I have a classic RT with lvl 10, Mid spring, #2 carrier, no shims, new PF plug, using a revo, 4-5 bounce paint, large bore barrel.
I can shoot slow and chop or get a barrel break, but when I shoot fast it gets even worse.
I can't use the long spring, I can't turn the velocity up high enough it just vents out the back (yes its the new piston)
Help?!

use the middle spring (red) then, or try different carriers that are hmm I think its larger to slow the bolt down umm maybe a forcefeed hopper would help

Switch the long spring and go up as many carriers as you can without it leaking. If that doesnt work then switch back to the middle spring (without touchign the carrier) and it might leak but just try it and if it does then go down a carrier again and maybe it will be fixed? I dunno.. also try putting some more shizims in there ;)
I put as many as I could in mine without it leaking.. it helps with short stroking on the ULT..
