Tuning Need Help guys (Reg's keep changing)

[KevinWood44]

OK so this is my 1st PCP, I bought the Impact M3. It obviously came factory tuned. The only thing I changed was I put on the Ernest Rowe transfer port.

Then I tuned it to: 

- 1st reg - 170 

- 2nd Reg - 145 (I bought the Sekhmet gauge and it was settling on exactly 145/146) 

- Hammer spring is currently on 12 (But I Haven't shot it much, I live in NYC so I have to find someplace outside the city before I can really shoot it) 

- Bottle is filled to 250bar 



So the problem is the pressure is constantly changing on it's own. So Saturday, the bottle was full at 250 bar, and I had the regs at 170 and 145. I shot it maybe 5-6x and the next day the bottle has already dropped to 210, the 1st reg is now at 200 and the 2nd reg now is at 197. I will attach pictures just so you can see I am not crazy.



What the hell is going on??? Any help is appreciated.

impacts are awesome rifles, but they are definitely not the most recommended rifles for newbies

I guess I'm just old and stubborn. This two reg thing reminds me of an old adage, "the perfect answer to a nonexistent problem."

Good luck in finding your issue, sounds like the FX folks might help.

I'm sure you have heard this before but it wasn't anything I did. Seems to either be a leak or a faulty reg. It isn't an issue I am having with tuning process (which admittedly can be a lot to learn for a new PCP owner) it's the fact that the reg is not holding the pressure. Could be as small as O-ring. I emailed FX, but they want me to get on the phone with them to troubleshoot some things with them.

A phone call is a lot quicker than a bunch of emails back and forth.

Yes, you should take advantage of the phone access. These things usually are not difficult to diagnose, but certain things often need to be done in a certain order, and it can be hard to walk someone through it by email.

It's probably the regs need break in and settle, put a tin of pellets through it and then see if the regs settle out.
