Condor SS setting it up and interpreting chrony data

[Bullseyeft]

It looks OK to me, but I  am not an expert either brother. I believe it is a valve issue due to when the Talon valve was in mine I had no problems of velocity inconsistencies. I had it shooting 24 shots at an average 760fps at 1% with MKII pellets. That's pretty much perfect for a stock AF Talon 18" barrel. I  wanted more velocity so I  added a striker weight and the Condor valve internals and the problem started with the inconsistencies.

I have it back together after receiving the parts from AF. I will be testing it out tomorrow morning and will post the results sometime tomorrow afternoon.My wife and I had to drive the 4 hrs to our daughters to help her move due to her getting a new job at JMU in Virginia.

Well the new parts AF sent me had no effect on the velocity drops. I  tried fills from 2600psi to 3000psi, I tried an oring and nylon washer behind the TH, I tried the PW from 5 to 8 and still have the same problem. I called AF and they want me to send it to  them. On my dime of course and they are going to charge me to fix it. So much for their warranty. I guess I will send it. They also gave me grief about the Talon Tunes QCTH , saying that the aftermarket parts may have something to do with the problem. Not sure if that is the reason they say it is out of warranty or not. I should have been happy with my Mrod and not even messed with AF. I will let you know if they get it fixed and how much it costs me. Completely Frustrated and ready to wrap it around a fence post.

Hey guys,  I have some promising news on the Talondor velocity issues. Olly sent me a PM as he is experiencing the same issues that I am. We have kinda been tag teaming this issue. Olly retried his AF TH and made some progress. So I  tried the same. Below is the string I shot this morning.
.25 Talondor
JSB MKII 33.95gr
TH - AF gap .120 with .033 nylon washer and 1/16 thick oring behind TH
PW - 8

The funny thing is there were no 50 - 100fps drops at all. I looked at the Talon Tunes QCTH and nothing looks abnormal or bent. I had tried the different restrictors and nothing made any difference until I pulled it out and put the AF TH back in. Then like a miracle it settled down. I don't know if the TTQCTH is defective or not but it was definitely the issues cause. Don't get me wrong I am not slamming Tony or his products. It is kinda weird that Olly had the same issues with the same product. I will be shooting some more strings just to be sure.

A great result Jim, I'm so happy for you, well us actually

I've only shot a few strings which is why I haven't published my results but it does look very promising and I've come to the same conclusion as to the the TTQCTH being the cause.

That said I think that the the TTQCTH is a brilliant bit of kit, that offers many advantages over the standard AF TH as those b*$$dy tiny set screws and I'd like to try another one

I have the same 33.95g pellets that I haven't had a chance to try, I'll give them a try this morning and compare results with you

I decided that I wanted a little more velocity, my targeted velocity was 850fps. I adjusted the PW to 9 and played with the fill pressure. I ended up with the following.
.25 Talondor
TH - AF factory - gap .996 with .03 nylon washer & 1/16 thick oring under TH
PW - 9
JSB MKII 33.95
3000psi fill
I got 39 shots at 2.25%
ES - 18.25
SD - 4.79
AVG FPS - 823.0
FPE - 51.1
HIGH - 831.6
LOW - 813.1
I am very happy with this setup and plan on leaving it right where it is. I did notice that around 835 - 840 the gun gets a lot louder. So I am settling on where I have it. I really don't need more than 51.1 FPE anyways and this is a good balance of power and quiet, plus I  can get 39 shots on 1 fill.
I imagine that the Kings will be doing around 900fps. If I have a need for speed and noise, I will just switch to the Kings.
I spoke with Tony last night and I  am sending back the QCTH for a replacement. I  hope it doesn't have the same issue as this one. I will try the replacement when it arrives and report back with the results. Thank you Tony for being so understanding.
Thank you Olly for your information sharing.
Now to kill some of these groundhogs since it is now worked out.

UPDATE
I received the new AF TH and installed it after setting it to .984 (from bottom of TH to bottom of valve stem) then red loctited it and the set screws and let it dry for 2 days. If I have to replace it, I will buy another one from AF and do the same to it. Placed a .025 nylon washer and a 1/16 thick poly oring under the TH. PW on 6. MKII pellets. 2800psi fill. I was able to get 30 shots at 2% with an average of 848fps and an ES of 17fps. Laser accurate now. I found that there was some clipping in the shroud. It blew 2 baffles on the end. I  cut some thick plastic and sanded it to fit in the baffles and glued in place with Plastic Weld epoxy. I also added some thick felt to a baffle and some to the end cap. Even at 848fps it is still backyard acceptable. The RL shroud is doing a great job on the noise now. All in all it was quite frustrating but it's all good now. My hunting partner will be back from the beach this week so look out groundhogs.
 
I sent the QCTH back to Tony and he emailed me that it was not in the envelope. So I guess we will see how that ends up. I requested a refund for the purchase price instead of the replacement as I have no interest in using it and having to go through this again.

UPDATE
Tony refunded the purchase price of the QCTH. It is all good now.
THANKS Tony !

You've got an excellent result, I hope I'll be able to get the same sort of success.
I still hope to get the TTQCTH to work, Tony's going to exchange this one for me. If it doesn't I'll be doing the same thing or looking for a one piece.
Any how nice one Jim

Anyone measure the OD the TT stem?

Was surprised to see how ruff the finish was in the pic. If it's not smooth and the fit is on the tight side that could be your problem. The o ring only need to barely be putting pressure on the stem. It's just there to stop the air on the shot.

Also I have noticed some valves don't work smooth when compressed with your thumb.
The return spring is so tight that it's making the valve bind. Make sure the valve is smooth working. Try turning the stem or he spring retainer nut to move things around. Valve should be smooth when compressed.

Its packed up ready to go in the post back to TT but I'll measure the new one when it arrives. What should it be?

Good info thank you

I'll check it all out for smooth operation when the new one arrives.

Rotating the stem I understand but I'm a bit confused about "turning the retainer nut" Isn't the spring retainer nut static and loctited in place?
