So as I've posted previously, I bought a bunch of paintball stuff and
included in it was a palmer stabilizer that I decided would find it's new
place to live on my autococker. So I checked the stock reg and found that
it was set somewhere around 200 psi. Okay.. So I hook up the palmer and
adjust it's pressure down to around 200psi and air up my cocker and give it
a whirl. All in all, everything seems to be okay but the paintball is
falling off sooner than I think it should, so I'm thinking, I need to turn
up the velocity a bit. So I didn't mess with the velocity spring, instead,
I turned up the input pressure. As I turn up the regulator pressure, the
velocity drops. I mean, the ball woudln't even reach 20 feet, much less
50-100 feet. So I turn the presure back down and velocity increases again.

I'm not sure what to think though the symptoms I'm getting are kinda
counter-intuitive. Anyone have any ideas what's going on? Do I have some
kind of flow problem?

1) the reg is counter threaded (my ion's reg is)
when you "tighten" it, the output pressure goes down

2) is there an lpr on your cocker? maybe that's set weird?

That would explain why the gauge on my reg goes up accordingly.

The LPR governs the front pneumatic pressure to the ram, not the air
pressure that launches the ball.

I've read on Otterssccustoms that if I set the input pressure too high, then
the valve won't stay open long enough, though I was setting it at 300psi
based on the micro gauge. May not be accurate enough.

The first thing that springs to mind is that the palmer's stabilizer has a
ramp up/ramp down/ramp up setup. If you turn it out too far, it seems to do
what you're describing. Crank it in(while the velocity drops) and then it
SHOULD go back up again, as you reach the next level of pressure.

The next thing, and this is unlikely, your cocking rod could be coming loose
during firing. Might want to put a spot of loctite on it once you get your
velocity dialed in, and just adjust with the stabilizer.

The most likely version is the step up/down/up thing that Palmers has going
for it. Just screw it in more than you think you should. Eventually it
will either bottom out, or your pressure will increase.

The other thing is this: are you SURE the pressure from the stock reg was
set at 200psi? That sound AWFULLY low for a stock or even modified cocker.
Most cockers have an operating pressure upwards of 400psi at least. I
wouldn't want to be responsible for telling you to massively INCREASE the
pressure(thus blowing every pneumatic device in your gun), but still, it's
something to consider.

you can overpressurize the valve which will make it drop back down.

what you need to do is sweet-spot the reg then adjust the velocity screw
from there.
