Epoch HP Reg Pressure drop?

[Tricky-Ricky]

I am experiencing reg pressure drop in line with bottle pressure, I was under the impression that the function of the regulator was to keep the pressure constant until the bottle pressure is reached, but this is crazy, this is a sub 12 .177, but this should make no difference today I filled to 4500psi which results in an HP reg pressure of 1500psi by the time I had shot down to 3000psi the HP reg pressure was just under 1100psi this makes no sense? And once it goes lower, the velocity starts to drop.

Also, does anyone know the air path through the Epoch regulators as I just can't seem to trace just how the regulation is carried out and why this is happening?

I'd give Skout a call....they will walk you through it.

It sounds like the regulator needs rebuilt. The ones l. have done were pretty easy. Taking pictures help.
