Condor data, with and without an o ring
I am new to this forum and new to the condor. I have gained a great deal of insight here and want to share what I have learned. I ran some chrono tests with my new .22 condor with a 24″ barrel.
With 25.4g JSB’s, PW setting 0, factory TH setting and a 2300 PSI fill I got the folowing data:
996,992,983,986,986 down to 2210 psi
986,1002,1002,1002,1002 down to 2020 psi
1020,990,977,980,960. down to 1800 psi
948,938,927,916,915 down to 1600
I ran some strings with a 2400 fill and the PW at 2/0 with the following:
velocity started at 1030 and ran an almost linear decent down to 906 after 20 shots, accuracy was so so
I then put a small o ring behind the stock set TH, 2500 fill, with PW at 0 and got the following:
880,879,875,855,867-2410 psi
939,955,962,972,973-2340 psi
978,976,980,943,966-2230 psi
980,978,973,973,965-2150 psi
at this point the light was getting tricky and the chrono stopped working but I shot another 10 shots with no POI shift and ended with 1980 psi in the tank. 2500 to 1980 psi with 30 shots and the same POI.
It seemed like the o ring calmed the gun down and used a lot less air.
When I dial the gun up it runs to hot, opens up the groups and uses tons of air. The o ring strings resulted in some unexplained fliers, reason TBD.
I have the new adjustable TH on the way from TT and will report.

TAG is the “Hotel California” of airguns;
I heard the mission bell
And I was thinking to myself,
“This could be Heaven or this could be Hell”
Then she lit up a candle and she showed me the way
There were voices down the corridor,
I thought I heard them say…Welcome to Talonairgun.com
😆 😆
Thanks for the welcome!
I just got the new top hat from TT, I have the big insert in it and only had time to blast 20 shots over the chrono. Much less noise!
With PW at 0 it puts the 25.4 out at 500, at PW of 8 that moves to 900. Its using much less air. I have cleared my afternoon Friday to do some proper testing and will give a full report on a new thread by Saturday.

Shhhh…..
Not to loud about the o-ring trick, AF might catch on 😆
Tony’s New valve will already be polished so that may take care of the occasional flier.
Otherwise, It’s easy to not get the breech fully on the top hat causing irregularities.
Good report, will love to see how you do with the new valve.
Yep! ya can’t miss fast enough to win in a gun fight! 😉
N3486N- that sounds like some of my customers….
“take your time but hurry”
remember what Waytt Earp said, “Speed is good; accuracy is better”. :thumb:
I should have the TT adjustable TH in a couple days also
thank you sir. I am using the 25.4g JSB
Meant to ask what pellet you were shooting too. 😀
I’ve found that the magic number is around 850 + – for flight stability.
I’m sure you’ll get feedback on the FPS 😆
I’m currently shooting the H&N 21.4g 5.52mm. It’s a pellet my other .22 rifles shoot the best. The good news is for me, my Condor is not really picky. It and my SS will shoot just about anything good, some better than others. Thank you Mr. Lothar Walther. 😎
Your results are right in line with my experiences too. I found the O ring helps flatten out the shot curve in some cases.
I think what the O ring acts as is a “hammer debounce device” to use a term found in the Marauder haunts.
However, watch for the O ring to deform at some point. The higher the PW or smaller the TH gap, the more flattening out of the O ring you will get. No big deal, easy and cheap to change. :thumb:
Keep shootin’ and the updates comin’!

what was your top hat gap before the o ring?

Fliers are from your power wheel being to low, not matched well with the psi in the tank. i have had better luck with no lower than 3 to 4 on the power wheel.
close gap on top hat to slow it back down after raising the power wheel.
