Upgrading from .177 to a .22 , need help
Hi all,
I guess this has been discussed before but need fresh opinions. I have a .177 condor with the dedicated .177 valve (harder valve return spring). Now I am considering an upgrade to a .22 . My question is that if I just change the barrel and retain the .177 valve return spring , what numbers can I expect. My guess is that with the harder valve return spring the .22 wouldnt be able to shoot to its full potential. Please chime in with some data if someone has done what I am planning to do.
P.S. Is there a specific name for the tool which is used to remove the valve of a condor from the bottle.
I will really appreciate any help
Sid

Well, I’m enjoying a TT 12″ x .177 barrel in my previously 24″ x .22 Condor with hammer spacer removed and an o-ring behind the top hat and, no tank dump.
So AF said no problem going from .177 to .22, just slightly slower FPS. Ya just can’t beat the fun we have modifying these great AF air rifles ❗
I have a 177 high flo I was going to shoot in my talon 22 ss with 21″ barrel. The talon tank with stem bored out shoots so much stronger. I have to put a lighter spring in the high flo. I got to wondering if they had sent me the tank to shoot less power but they didn’t. It is just the heavy spring.
what they said 😆
Here is what Airforce told me about this ->
” Your .177 hi-flo tank will work with a .22 caliber barrel, however, it will reduce the velocity approximately 50 – 100fps. The reason being, a stronger valve spring is installed in a .177 hi-flo tank than for a .22 hi-flo tank. But the .177 tank will work with the other caliber barrels. You can not use a .22 caliber hi-flo tank with a .177 caliber barrel because it will cause the tank to dump.”
Hope this helps!
Oh most definitely with the 25, it is an air hog, and the 22 is too as the pellets get heavier to keep up the velocity. I have used as little as 5 psi per shot with 14 grain pellets at 800’s , while the 32 grain eunjin at 1000 fps use’s like 100 psi per shot. or something like that
the 32 g. eunjin are the heaviest pellets that i have used in 22.
powderburner: your comments match my understanding of this as well.
Lady at Airforce was clear when she said approximately 20% loss in max. vel. Stiffer valve means less air comes out. My understanding is that the .177 Condor needs a stiffer valve spring to prevent tank dumps.
So I guess it is an issue only if you want to hot rod for heaviest .22 pellets (how heavy can those get?). Or if you got to .25 cal and don’t switch out the tank.
I need to post my shot strings to show you all what mine does and get opinions.
So airforce said you would not be able to shoot as fast with the 177 condor valve spring set up when shooting .22 , ????
1050 or so is super sonic , and the condor will go 1400 fps with the 14 grain pellets and maximum settings.
so i was about right , the 177 condor set up will shoot 22 fine except if you want to hot rod the heavier pellets, ?
I have the same question as powderburner for Walkonking: I have the same setup, 24″ Condor with the .177 tank and .22 barrel. I use a Hill hand pump and am able to get the tank to 3000 psi if I want to. While I have not fully figured out my strings I have not noticed any unusually small shot counts. With the power wheel turned up I can easily go supersonic with 14.3 gr. .22 Crosmans. A call to Airforce told me that all I can expect is about a 20% reduction in max. velocity.
Why is that Walk. your saying that the valve return spring is going to keep him from getting a full fill up on his bottle.
I would think that with light pellets it might work out nicely, but i am thinking about my 24” condor and turning the valve down for lighter pellets at 900’s but with the short 12” SS you have to keep the valve open for decent velocity and waste air to achieve it , wouldn’t you??
I have only had the .22 Condor . , have you shot .22 with a .177 condor tank set up.??
Well actually he doesn’t say what barrel length does he, was thinking about another thread
get a spanner wrench
You will not be able to get a full fill on your tank and will get many less shots with that heavy valve spring.
You will probably be just fine on the velocity with the .22 ,with the .177 spring on the valve.
unless you are trying to max out the heaviest pellets.
with most pellets you are well below max velocity for the condor anyway for best accuracy.
Yes there is a special tool name for taking off the valve from the tank,
Big frigging pipe wrench. 😆
Marmot_Militia makes a tool to remove the valve. but i would try it with the 22 before i pulled it .

, you trying this out yet, let us know how it’s working out, ????? 🙂
Hey Lurk ;
