I have a new dreamlite tactical on the way and am thinking my WC II might go in the classifieds. I want to describe to a potential buyer what issues, if any, there are with the gun. However, it is acting consistently strangely. All POI are the same for both outings. Starts 3" low, but centered and gradually keeps moving up until in center of bull happens about shot 4. Then there is a good group. Dime size with a slight wind. At 50Yds off a bench through a Caldwell Chrono. Heres the data:

Start 230 Bar Start 190 Bar

1. Err 3 1.Err 3 Don't know why the 1st shot is Err 3.

2. 828 2. 829

3. 845 3. 838

4. 858 4. 851

5. 868 5. 857

6. 859 6. 860

7. 859 7. 854

8. 860 8. 863

So what's my issue? The gun loses no pressure. But every time I go to shoot I have to shoot 3 shots before I can believe I have the accuracy I need. However, I don't know if that repeats itself after the gun has been inactive for 1 hour, 1 day or whatever. Too damn cold now to go test every hour. Any help, like always is respectfully received. Thanks!
 
I've had the same with my FX impact and perhaps others. I"ve noticed this after filling the air chamber. Seems like it takes time for the regulator to settle down (if that's the problem and I can't guess what else it would be since that's all that was changed) . It's a bit of a problem for a hunting gun.. My gun often shoots high for a shot or two and then will group nicely. I can't tell you what the chronograph reading might be.

Hope some one can provide more information for us.

Well I must be honest that I have zero experiense with WC but I would imagine its regulator slowly creeping and filling to a higher pressure than what hammer can open and what reg is set at. Thats why ur first few shots are slow untill pressure inside ur regulated chamber lowers enough to a right set level so valve can fully open. Thats the only explanation I can fiqure out but since I have no idea how WC works and what size that chamber is this is only a bad quess but atleast before FX regs had bad habbit to creep in time and also hammer force was kinda optimized for max reg pressure and not able to open valve fully when going above that certain set max pressure.

Aloha,

OP, I have had the err3 on my Caldwell chrono also, I called tech for help and they said it has to do with the last sky screen picking up the projectile . They told me to make sure the screens are clean then turn off & turn back on to reset it. I did this procedure and it helped but every once in awhile I get the err code come up. Hope this might help you out. 

As for the low numbers my WC mk2, I had to send it in for warranty on what you are describing. FX said it was the regulator. 

Aloha, Keone

What you’re experiencing is regulator creep. After a fill or if the gun sits a while. High pressure air leaks by from the air cylinder or bottle side past the regulator’s seals or piston enough to raise the plenum pressure. Which alters the consistency of your tune and changes the POI. After a handful of shots the regulator settles back into its set pressure and shoots more closely to it’s set tune pressure. A couple of remedies would be to rebuild / re-seal the regulator or replace it. Just the nature of mechanical devices sometimes.

Watch this video it may lend some understanding?

my WC did same exact thing , I had FX send me a new reg and it fixed it , I had orher FX do it and a HUMA reg fixed it , I am sure People here know it does it internally but if you do not have a FX reg tester , Send it to FX or get a huma

You can take out the brass screw on side of action and put a gage there fill gun and you will see the regulator creeping , but if you change settings with out reg tester , you got to assemble gun and fill to see , alot of wasted time and air , The FX regs wont Fit in huma or the Edgun regulator testers
