Help: Problem developed with FX Impact

[Longbrownbox]

Pulled out my Impact that I haven't shot in 6 mo. Previously shooting fine but now is shooting under 400 fps. Tank is at 230 bar, power setting is 5 just under max, valve is 2 1/2. I do not feel any unusual air when I shoot but it just doesn't have any power. Chrony shows 340 & 380 on max. Shooting .25 cal. but lower results on .30 cal. Suggestions other than sending it to AOA? Regulator pressure 150.

What reg pressure 

 

[Longbrownbox]

Sorry, should have included that. Gauge shows 150.

Check to make sure your transfer port is lined up to the port in your barrel. The barrel may have rotated out of alignment slightly.

Remove bottle and bleed reg side, reinstall bottle and test

True on some AG but vary unlike with the impact:

There's a groove on barrel and pin on the action that mate up when barrel in place to insure TP are aligned and prevent barrel from rotating, plus the barrel lock down screw also aligned the barrel TP and proper distance to the mag.

E, when I remove CF bottle, both gauges go to zero. Does this accomplish what you suggest? 
The barrel is properly aligned. I removed the side screw to verify proper indexing. Not sure what to do.

Some don't require bleeding --- after reinstall the bottle what's the reg pressure??? Did you test speed??

 

[Longbrownbox]

Reg pressure goes back to 150. When I take off my bottle both gauges go to zero. I've read that some Regs hold pressure for a time. My .25 cal shoots 340 fps. About 380 on max.

Back out VS to 4 and test for speed!!!

 

[Longbrownbox]

E, I screwed the VS well past the last white mark. It shot with power. My chrony wasn't working but I could tell it sounded normal. I backed it back down to 2 1/2 and started stacking pellets. It must have gotten stuck somehow. Anyway thanks for the heads up. Will put the .30 cal on tomorrow & ck it out. 

 

[Longbrownbox]

What FPS should I be getting on .30 shooting 48 gr pellet?

I think that you may have old pellet in your probe so the air cant go to barrel.
I have that issues when i cock 3 times my impact when test modification of magazin and i thought that all of pellets go to barrel but jsb is so soft that last one go to probe.
or you left cocked for this time and the spring is killed ;P
