Reg creep

[Kamanthi-]

Hi everytime I take my Dreamline tactical out to the range my first shot is Around 812 fps then second goes back to 870
fps the reg is on around 110
And it stays consistent so could someone tell me what the problem might be this is a pic it’s the newer version with the power plenum

@Kamanthi- I’m not familiar with that rifle. Does it have a manometer for the regulator? If so, do you notice that it moves from its initial setting throughout a shot string? What’s the starting and ending regulator pressure setting?

Thanks for the recipe!

Echoing what @Ezana4CE said, is there a reg gauge on that gun?

Mmmm, king prawns!

It’s creep. But at least it looks like your hammer setting is close. Go up one click on your hammer wheel and see what happens. You still have some wiggle room with your speed only being 870fps. This is not a fix for creep. It’s more of a band aide. My DL creeps a little also.

Need more hammer strike, lower reg pressure or both to tune out the creep that's happening. Depending on your target fps.

The reg pressure is on 110 and when I shoot it it goes back to 110 yes it has reg guage

@Kamanthi- Goes back to 110? Does it move or remain at 110 the entire shot string?

No it moves a little like all regs when shot then it goes back to 110

The reg stays the same 110

when I shoot it it goes back to 110

And holds at 110 bar after it has sat idle for a while? By “a while” I mean a few hours, or however long would represent the first shot to you.

If it holds at 110 bar indefinitely, the regulator is not creeping.

Another known cause is O-ring stiction, at least on the Impact. I don’t know if the Dreamline has the same arrangement.

Tuning - FX Impact Mk2/M3 - slower first shot - no reg creep - quasi-scientific analysis

Hi guys, Welcome everybody. This is my first post here. I have a problem with my Impact Mk2 PP .30. The reg pressure is 145 bars. When I shoot shot after shot then my v0 is 260m/s. However, when the gun sits for a couple of hours then the first shot is 250m/s despite the exact same reg...

That slower first shot could be , just a guess, that it goes from a warm house to a cooler outdoors. The air contracts when it gets cooler ? You could just take one shot before you get too serious.

Yes stays solid on 110

Yes their is a reg guage and it stays on 110
Even when I don’t shoot it for 2 weeks

 

[nervoustrig]

That being the case, some source of stiction is the next most likely cause as stated above.

Hi my hammer setting is on 22 I think the highest setting

Hi my hammer setting is on 22 I think the highest setting

I have only shot let’s say 180
Pellets through it as it’s a brand new rifle

Yikes. Who set up the gun?
