FX Impact creeping velocity

[Arash]

Hi

I had the exact problem. First shoot was slow then raised to its normal speed.

Download impact charts. Search for B23 which is a oring. Lubricate it.

I hope it works for you too.

Carbon shroud is a Airfective stage 1, very quite, great quality and does not look too heavy.

Cheers for the advice BarNone, rifle now rebuilt with new reg pistol, testing and tuning tomorrow.

Hi frank320

Did you watch for velocity drop as you turned the valve in or did you look for consistency ?

Interested in how you solved the problem.

Cheers

Great question. I just sent FX USA the following question:

Assuming I am shooting at the velocity I want, should I then:

1) adjust the valve control knob clockwise/inwards until till velocity drops, then back off?

or

2) adjust the valve control knob counter-clockwise/outwards till velocity drops, then back off?

I will update back here with their response once they get back to me.

Update from FX USA/Newman:

"Ernest says your process is right, and you turn the knob clockwise/ inward until the velocity drops, then back it off. The knob does control air efficiency."

Quite impressed with Airfectives shrouds, I like the look of the stage 2 as well, Can't beat a bit of carbon fiber.

Anyway, Good luck with the testing

After an initial setup it's now running very well with a standard deviation of 2.5, well pleased. No creep. Mission accomplished!!

Thanks guys for your advice on this issue. Cheers an merry Christmas

Just bought this, Daystate Wolverine R in 177. Very good, very different from the impact but that was the point.
