Before I buy a CFX .22....

LMAO!!

Oh great... I opened up a hole for any post now. You said previously in the thread that you have a chrony coming. So when and where is the party? You just wait...you'll see. When I got my chrony, I stayed up all night playing with it, the possibilities are endless, especially if you are a tekkie like me. Just remember to put some protection in front of it, so that when the PBA ammo goes wild, you won't have a hole in your chrony. And I'm thinkin Stephanie needs one too so she can measure stuff. Check out how fast your hand is...move it through both sensors and I bet you'll be suprised how slow your hands are and you cant make them much faster. Thats what I did when I ran out of guns, pellets, and situations to chrony...

[davee1]

Thanks Vince for that reference...I had never seen that before. I read through it and there's something wrong...there must have been a change in the 2007 models because there is no way that the rotary is going anywhere to change the front seal. It looks to me like disassembly is the only way I can check everything. When you said that you wonder if my spring might be "short" did you mean that it could be broken? Or actually physically short in length? It has an awful twang to it. The first shot out of the box was a detonation, followed by smoky deiseling shots, and then finally she settled down to barely any smoke at all which is where she's at now. I got this beauty less than a month ago from Pyramid, which apparently is the only place that has the .22 version. Total shots through it is about 200. I havent been shooting it much, because...well...I'm kinda mad that I paid 220 bucks for it and its just not what I was expecting. Its a beautiful gun, cocking is smooth, but the power is really disappointing to me. I'm starting to get that sick feeling like I did when I got my Hammerli X2.

If'n my figures are correct, your gun is delivering between about 14 and 23 ft-lbs of energy, depending on the pellet. It also seems odd that it shoots the FTS so much slower than the much heavier Crow-Magnums.

Yeah, that is strange.
I have found similar anomalies with other airguns.
Even though the Crow Magnum is a rather heavy pellet, while the FTS is significantly lighter, the former is faster.
I am guessing that there is more at work than simple weight ratios, such as how tightly each respective pellet fits the bore, how efficiently a given pellet harnesses the spring piston, lubricity of each pellet, etc.
To further surprise you, my .22 CFX actually shoots two types of pellets FASTER than the .177 CFX versions of the same pellets.
JSB Exact (.177) - 754
JSB Exact (.22) - 767
Beeman Ram Jet (.177) - 713
Beeman Ram Jet (.22) - 735

Furthermore, it also shoots two other pellets so close to the .177 versions that it is probably overlapping and either the same or higher with the .22 again (I didn't go to the trouble to shoot several of each pellet, then average, I simply shot two or three to "wake up" my rifles, then shot one of each pellet over my Chrony).
JSB Predator Polymer Tip (.177) - 778
JSB Predator Polymer Tip (.22) - 756
Beeman Kodiak (.177) - 715
Beeman Kodiak (.22) - 704

From all this data, it seems that the .22 is considerably more efficient in utilizing the energy at its disposal.
Oh, accuracy-wise, the .22 loves JSB Exacts (1/2" @ 50 yards), while the .177 seems to have a three-way tie between Ram Jets, Exacts, and Superdomes, all of which drop inside 1/2" @ 50 yards.
However, they each have pellets they do not shoot well.
In the .177, those pellets are the Gamo Raptor (no surprise, supersonic instability, something on the order of 1-1/2") and the Beeman Silver Ace (terrible, hovers around 2").
The .22 throws Silver Arrows so poorly that I am guessing somewhere around 4-5"!
Great airguns, and not very hold sensitive at all.
In fact, their firing behavior and handling remind me more of a .22 rimfire than a spring piston airgun.

Vince, are you thinkin most of the pellets should be going faster or slower?  I can chrony a few of my pellets as I have a CFX .22  I'll post those velocities in a little while.

RWS Hobby         750fps

RWS Superdome  630fps 

Is this good, or bad?  I thought that I would get like 800 out of it but no way.  There is no visible smoke coming from it and it has quite a twang to it.

My Hammerli Storm .22 is blowin out RWS hobbies at 783 and superdomes at 710fps.  I'm kinda disappointed in the performance of my CFX.  I paid 220 bucks for it and 133 for the Storm.  I don't get it...I love my Storm, it is my go to close range hunter.  But the CFX?  I'm looking at it and thinking, I should have never even bought it. 

 

 

Actually, I think you are being unfair to your .22 CFX.
Remember that each pellet gun has its own preference in pellets, and that applies just as much to how fast it shoots a given pellet as well as to how accurate it is with said pellet.
FWIW, my .22 CFX shoots Superdomes at 663fps, so your results are statistically very close, especially considering that you are probably basing those figures on a brand new gun that has neither been tuned nor allowed to break in a bit, both of which practices usually yield slight increases in muzzle velocity and accuracy, and decreases in roughness and twanginess.
I have blown over 2,000 pellets out of my .177 CFX now, and it is smooth as glass, hardly buzzes when shot, and is so accurate with most of the pellets I have that it is a real task to measure groups, as it likes to stack each shot on top of the last.
The .22 CFX is shooting very well, too, even though it is newer and has only had something like 700 pellets blown out of it, so it is far from fully broken in just yet, so its greater vibration, roughness, and somewhat lesser accuracy should all improve in about another 1,000 shots.
However, I DO believe that the .22 will always have noticeably greater recoil, but that is a function of firing pellets that often weigh twice as much as their .177 counterparts, so Newton's theory comes into play here.
One thing is for certain:  The .22 absolutely obliterates what I shoot with it, while the .177 usually sends pellets screaming through what I hit so quickly and with so much greater penetration that I hardly notice it.

[davee1]

Scott this is good stuff!!! Very interesting and surprising. And based on the fact that your CFX .22 is shooting Kodiaks at 704 and mine is shooting them at 550...well that just makes me think that my CFX is defective. And now I *definately* am sick. There's been a couple of airgun purchases for me recently that have made me sick. I'm going to have to be more cautious.

[davee1]

Scott, there's no way that I'm being unfair to my CFX when yours is poppin Kodiaks out at 700 and mine is doing 550. There's something wrong there.

Hmmm...gotta chrony comin' this way, will fps my .22 cfx and .177 cfx.  Maybe everyone with a cfx .22 should post their chrony results with different pellets here too?

Hmmm...didn't pay attention to that.
It seems strange that the Superdomes are so close, while the Kodiaks are so far apart.
Could be something about your particular lot of pellets?
It seems unlikely on the surface that the airgun itself is at fault, seeing how close the Superdomes are, but then I am no expert on these matters, preferring to allow my airguns to break in over time than toss another $150 or so to someone to tune them by hand.

[davee1]

Are you thinkin that a break-in is gonna boost up the velocity on a 21 grain pellet by 150fps? Let me chrony those Kodiaks again to make sure that my eyes were right...

nope.. 4 shots 545~557

davee1 - 9/16/2007  11:32 AM

Scott, would you be willing just to test your Barracudas over again?  They are the heaviest pellet of the bunch.  I'm getting 550fps with Kodiaks, which are the same as barracudas.

Roger that.
When I get a chance tomorrow, I will Chrony Kodiaks out of each CFX.
btw...I have to say that all this angst over muzzle velocity is a little over the top.
If there really IS something wrong, call Pyramyd Air, and see if you can't talk to one of their techs.
Their support is excellent, and their return policy is outstanding.
They REALLY want their customers happy.

Well, some people have actually taken out their F-1 Chrony at short range when they bobbled their Ruger Blackhawk .45 Colt, nuking it with a maximum charged 200 grain lead semi-wadcutter, necessitating a return to Shooting Chrony for a $50 repair.
Hmmm...I wonder who could possibly be so dumb?
 

[davee1]

What do you mean...angst? I will call Pyramyd when the time is right, but first I would like to determine if there is indeed a problem by comparing numbers with the heaviest common pellet, which I see as the kodiak. I am often silly, and that sometimes is misunderstood.

[davee1]

exactly :-)

It happens...thats why Ive got a 4x4 block of wood protecting mine...

Reminds me...need to pickup some railroad ties.  .50 Armalites do bad things to "stuff". :emoticon:

I do have one coming from Cheaper Than Dirt.  Should be here in a few days.
