All teh pews
RT pressure problem, help please!
I have a classic RT and heres the deal. When I gas it up it will shoot 2-3 shots fine, then build up pressure and leak out the back. One shot and its fine again. At the chrono its like 275, 278, 360, 275, 279, 367...I'm not sure what I need to replace, help would be greatly appreciated! thanks!

In a classic valve it would most likely be the regulator seat. Not sure what it looks like or where it is in the RT valve.
My guess is replacing the o-ring here will solve the problem (note the picture was stolen outright from an animation on ZDSPB.com): http://www.mcarterbrown.com/gallery/...php/photo/8495

You aren't using CO2 are you?
In case you are, you shouldn't because the RT valve recharges so quickly that it heats up. This heat would cause CO2 to expand and over-pressurize the valve, showing the symptoms that you have described here.
If you aren't using CO2, a rebuild of the reg might be necessary.
