upgrade whisper with a gas ram ?

[Checco]

Hello all,
I have a new  Whisper I bought  2 months ago & all ready  ran about 4000 .177  pellets through it & it has lost power.
Whould it be worth it to have it upgraded with a gas ram & tuned.
If so who & how much. I live in california in the bay area.
Thanks for your insight & experience

You should send it back to Gamo for warranty.

I can't I believe I voided the warranty because & put the trigger in it.

All you would need to do is reinstall the factory trigger in it to send it back.

thanks

Does anybody have any idea why this rifle might of failed? I called P/A & asked them if the JSB exact heavy were ok & they said they were OK. That is the most accurate pellet I could fine. I went through a few.
I put the gun on a scale this evening & found that it lost 10lb. of resistance cocking it. New it was 30-32lbs now it is 20-22 lbs. Also when I bought it I had shot through a piece of 1x4 pine & it blew right through it a @ 4 yards. Now it will only penitrate flush @ 4 yards.
Its going back. I was thinking of just Having a nitro piston Installed but now I thinks that they need to replace it. When I come home with another should I use lighter pellet?

Most likely a broken spring.

Installed the original trigger back this morning & took the rifle back to
Big 5 sporting goods today, Got my cash back &
Purchased the new Benj.Trail NP .22 from P/A
Hope it makes me happy. I Checked Bob's site &
it looks like the trigger I have will also fit this.
Looking forward to this new Rifle.
P.S.
I bought that Whisper while it was on display, I wonder if it had been  dry fired  ?
I guess we will never know.
Don't even matter.
